Abstract:

Kebutuhan energi listrik domestik mayoritas berbentuk gelombang sinusoida pada frekuensi 50 Hz. Sumber energi terbarukan mayoritas berbentuk dc atau daya dengan frekuensi tidak terkontrol. Untuk itu diperlukan alat yang dapat mengontrol bentuk gelombang dan frekuensinya. Alat ini disebut inverter.

Dipasaran tersedia pembangkit SPWM seri EGS-002, modul ini beroperasi pada frekuensi tetap 50 HZ atau 60 Hz, sehingga tidak bisa digunakan untuk membangkitkan daya listrik dengan frekuensi yang variabel. Untuk itu dilakukan penelitian ini, tahap awal adalah membuat pembangkit SPWM berbasiskan arduino dengan spesifikasi semirip mungkin dengan EGS-002. Sistem yang dibangun terdiri dari arduino uno sebagai pembangkit sinyal SPWM, driver IR-2110 sebagai penyedia tegangan mengambang (bootstrap) untuk transistor MOSFET tipe-N IRZF44N pada rangkaian H-bridge. Hasil yang didapatkan adalah mikrokontroller arduino uno bisa membangkitkan sinyal SPWM dengan hasil berupa gelombang sinusoida murni dengan frekuensi 50 Hz.  Domestic electrical energy needs are in the form of sinusoidal waves at a frequency of 50 Hz. The majority of renewable energy sources are in the form of dc or power with uncontrolled frequency. For that we need a tool that can control the waveform and frequency. This device is called an inverter. The essence of the sinusoidal inverter lies in the switching control, where the waveform and frequency are determined by this controller, one of which is the SPWM wave. In the market, there is an EGS-002 series SPWM generator, this module operates at a fixed frequency of 50 Hz or 60 Hz, so it cannot be used to generate electrical power with a variable frequency. For this reason, this research is carried out, the initial stage is to make an Arduino-based SPWM generator with specifications as close as possible to the EGS-002. The system built consists of Arduino Uno as a SPWM signal generator, IR-2110 driver as a floating voltage provider (bootstrap) for the IRZF44N N-type MOSFET transistor in the H-bridge circuit. The results obtained are the Arduino Uno microcontroller can generate SPWM signals with the results in the form of pure sinusoidal waves with a frequency of 50 Hz.

Abstract:

SVPWM (Space Vector Pulse Width Modulation) technique is type of traditional PWM method that efficiently utilizes its dc link voltage and generates high voltage pulses with low harmonic content and high modulation index. VSI (Voltage Source Inverter) with SVPWM generates adjustable voltage and frequency signals for VSDs (Variable Speed Drives). This research work presents the simplified SVPWM technique for controlling the speed and torque of induction motor. The performance of developed SVPWM technique is analyzed in terms of its switching losses and harmonic content and compared with SPWM (Sinusoidal Pulse Width Modulation). Mathematical modeling for induction motor control through two-level VSI with SVPWM and SPWM is presented. The voltage and current TDHs (Total Harmonic Distortions) of the drive with SVPWM technique are 73.23 and 63.3% respectively as compared to 101.99 and 77.89% with SPWM technique. Similarly, the switching losses with SVPWM technique are 178.79 mW and that of with SPWM are 269.45 mW. Simulink modeling and laboratory setup are developed to testify the efficacy of SVPWM and SPWM techniques. The modulation factor of SVPWM technique is 0.907 which is higher as compared to SPWM technique with 0.785 modulation factor.

Abstract:

The thesis mainly proposed a novel design method for Sinusoidal Pulse Width Modulation (SPWM) controller based on modulation waveform cycle normalization. T is the period of sinusoidal modulation waveform, and T/n is the cycle of triangular carrier. Shift registers and adders of SPWM controller were designed to translate the 2n numerical value for SPWM waveform on-off switching points, which were calculated offline, to control the level of the outpout SPWM waveform,which is the key point of modulation waveform cycle normalization. In the thesis RTL function simulation verification by ModelSim and testing for FPGA have been achieved successfully. The results show that the novel SPWM controller is reliable, which has practical significance.

Abstract:

Inverter and rectifier controllers frequently employ the space vector pulse width modulation (SVPWM) approach. The space vector pulse width modulation is more suitable for digital implementation than sinusoidal pulse width modulation (SPWM) and can enhance the achievable maximum output voltage, with maximum line voltage nearing 70.7 % of the DC link voltage (compared to 61.2 % for SPWM) in the linear modulation range. It can also achieve a lower voltage total harmonic distortion factor. In this work, we apply these two methods to photovoltaic systems based on technical dependence MPPT INC to improve the output voltage of the photovoltaic panel.

Abstract:

This article presents a carrier-based pulse-width modulation (PWM) template for a 5-level, H bridge-based cascaded multilevel inverter (MLI). The developed control concept generates adequate modulation template for this inverter topology wherein a sinusoidal modulating waveform is modified to fit in a single triangular carrier signal range. With this modulation approach, classical multiplicity and synchronization of the triangular carrier signals criterion for the extension of sinusoidal pulse-width modulation, SPWM, to several cascaded 5-level, H-bridge-based MLI topology are removed. The proposed template can be used on the inverter configuration of any level with no further control modification. Nearly even distribution of switching pulses and equalized individual cascaded cell output power were achieved with the proposed modulation scheme. Three 5-level, H-bridge-based MLI units were cascaded for 1-phase, 13-level inverter operation; simulation and experimental results are adequately presented.

Abstract:

This paper deals with a novel natural sampled pulse width modulation (PWM) switching strategy for voltage source inverter through carrier modification. The proposed inverted sine carrier PWM (ISCPWM) method, which uses the conventional sinusoidal reference signal and an inverted sine carrier, has a better spectral quality and a higher fundamental component compared to the conventional sinusoidal PWM (SPWM) without any pulse dropping. The ISCPWM strategy enhances the fundamental output voltage particularly at lower modulation index ranges while keeping the total harmonic distortion (THD) lower without involving changes in device switching losses. The presented mathematical preliminaries for both SPWM and ISCPWM give a conceptual understanding and a comparison of the strategies. The detailed comparison of the harmonic content and fundamental component of the ISCPWM output for different values of modulation index with the results obtained for the SPWM is also presented. Finally, the proposed modulator has been implemented in field programmable gate array (FPGA- Xilinx Spartan 3) and tested with the proto-type inverter.

Abstract:

Sinusoidal pulse width modulation (SPWM) technique has been widely used in inverters and motor driver ciruits. In this paper, SPWM was generated by a low cost HT66F50 single-chip, wherein the reduced sampling points of a sine wave, and the fewer sampling points were then used to produce SPWM singals. The full-bridge inverter was modulated by the high switching frequency SPWM for the high side switches and the 60Hz control signals for the low side switches. Thus, it not only reduces the required memory spacein MCU, but also reduces the switching power losses. When the SPWM frequency is 19.53 kHz or 11.72 kHz, the total harmonic distortion (THD) of the inverter’s output is less than 0.6% under the load resistance 50, which is in compliance with the specification of IEEE STD. 519-1992.

Abstract:

Space vector pulse width modulation (SVPWM) generates less harmonic distortion in the output voltage or currents, provides more efficient use of supply voltage and better voltage utilization compared with sine pulse width modulation (PWM). In this work, a detailed Simulink implementation for SVPWM for the open loop control of permanent magnet synchronous motor (PMSM) is presented. Results show the output of the blocks that assembles SVPWM besides the PMSM voltages and currents when exposing the motor to different load torques. The technique of SVPWM enables the load to respond to the change in external load torque. This technique also results in lower total harmonic distortion and better utilization of the direct current (DC) supply compared with traditional sinusoidal pulse width modulation sinusoidal pulse width modulation (SPWM).

Abstract:

This paper presents a comparison between two switching techniques namely Phase Offset Disposition Sinusoidal PWM (POD-SPWM) and Symmetrical PWM switching for a generalized current source multilevel inverter (MCSI) topology. One of the advantages of MCSI is it can reduce the total harmonic distortion (THD) at the output load current with a sinusoidal current waveform. In this paper, the generalized MCSI with the different levels has been developed with Matlab@simulation software in order to study the performance of the two switching schemes for the operation of the MCSI. From the simulation results, POD-SPWM switching technique can give better THD results compare to symmetrical switching technique.

Abstract:

This paper investigates the low order harmonics of a simplified approach to generate high quality sinusoidal pulse width modulation (SPWM) waveform produced by voltage source inverter (VSI). Programmable interface controllers (PIC) microcontroller was chosen to produce the signals in Real time with voltage feedback to control the puls width during direct current (DC) link voltage reduction. The research considered simplicity, durability, and reliability as conditions. The proposed technique was successfully passed one of the biggest challenges which is time criteria presence due to execution time of the feedback loop and the transient time required for power electronics switches to turn fully off and on, known as dead time. The proposed technique can be considered as practical, high feasibility according to economic point of view and its accuracy to the input variables.

Abstract:

In this paper, a modified sinusoidal pulse width modulation (MSPWM) technique and a modified single-phase H-bridge seven-level inverter is proposed. The switching pulses for the proposed seven-level inverter are generated using a single triangular carrier waveform, a fully rectified sinusoidal signal, and three stepped reference signals (Uref1, Uref2 and Uref3). Using optimization technique, the magnitude of the stepped reference signal is determined so that the total harmonic distortion (THD) of the output voltage waveform is minimum and the fundamental component, RMS value of the voltage is improved for a given modulation index Ma as compared to the sinusoidal pulse width modulation (SPWM). By the implementation of the new scheme, the seven-level of the inverter output voltage level (+Vdc, +2Vdc/3, +Vdc/3, 0, −Vdc, −2Vdc/3, −Vdc) is obtained for any given modulation index. Similarly, if only two stepped reference signals are used then the inverter will act as a five-level inverter for any modulating index Ma. The proposed MSPWM and seven-level inverter are simulated on MATLAB/SIMULINK for R, R-L load and on a single-phase capacitor-start and capacitor-start-run Induction Motor.

Abstract:

This paper introduces an approach that applies a digital sampling technique for a sinusoidal pulse width modulation (SPWM) multilevel inverter modulation that reduces the total harmonic contents in the output voltage compared to that of classical regular sampling techniques. This new modulation emulates with a high degree of fidelity a natural sampling pulse width modulation (PWM). The theoretical analysis of this new digital technique compared with natural sampling has been validated by simulations and through experiments with a built prototype that performed five–level inverter modulations with vertically displaced carriers in phase disposition. Both simulation and experimental results generate a SPWM output voltage with higher fidelity than classic regular sampling techniques, allowing a reduction of the filtering demands on the inverter output, which in turn can decrease the converter size and its manufacturing costs. As the presented technique is digital, the resulting modulation is more robust against switching noise, jitter, and other system perturbations and the modulation parameters can be changed easily, even in an automated way. For this reason, the modulation introduced here can be a useful tool to perform spectral analysis for different multilevel modulations and systems.

Abstract:

This paper explores the use of Space Vector Pulse Width Modulation (SVPWM) instead of Sinusoidal Pulse Width Modulation (SPWM) to evaluate dynamic response of the synchronous inverter (synchronverter). The paper presents a comprehensive comparison between the SVPWM and SPWM for the dynamic response of synchronverter. This comparison aspects contain: the grid frequency, the active and reactive power, line current and its THD and rate of change of frequency (RoCoF) in case of using both modulation techniques. Despite the complexity of using SVPWM, it has several advantages over SPWM. With the increased penetration of renewable energy sources in power systems, the system inertia is reduced, and the frequency deviations becomes greater and faster. The results of this paper show that SVPWM contributes to reducing the rate of change of frequency (RoCoF) which enhances the system inertia. The results show a more stable behavior of SVPWM than the SPWM. Moreover, SVPWM reduces the total harmonics distortion (THD) of the current by 7% as compared to SPWM. Furthermore, the use of SVPWM reduces the complexity and the cost of the used filter. Matlab/Simulink is used for results validation.

Abstract:

Harmonic content is an important parameter in relation to the power generated by inverter. In power conversion technology of inverter, sinusoidal pulse width modulation (SPWM) is the most popular used by many researchers. The advantages of SPWM inverter operation as a conversion technique compared to other inverter types can be seen from the low harmonic distortion in the output voltage of inverter. Therefore, the SPWM signal generation process becomes a determining factor for the performance of the overall system. This paper present the method for selecting the modulation index (ma) and frequency ratio (mf) using Cubic Spline Interpolation to get minimum harmonic of SPWM inverter that generated. Both parameters controlled with varied values digitally using microcontroller to generate SPWM, then the output of inverter with and without LC filter was investigated. The results show that the use of Cubic Spline Interpolation method in the selection of ma and mf precisely managed to produce SPWM inverter with minimum harmonic content. At the inverter output, the use of LC filter is not only useful for converting SPWM signals to sinusoidal waveforms but can also reduce harmonic content significantly less than 3 %.

Balanced split-input DC-link voltages were achieved through further incorporation of adjustable voltage-dependent variables into the reference signals. The dynamic performance of the control approach is demonstrated through simulations and experiments on a laboratory inverter prototype; the results are well presented.

Nowadays, the multilevel inverter has gained huge attention and has become more popularized in high voltage and high-power applications with low harmonics. As the number of output voltage increases, the harmonic content of the output voltage waveform decreases. In this paper, a comparison of cascaded H-bridge and cross-switched multilevel inverters for 7, 9, 15, 21 levels will be carried out. The different control techniques that will be used for carrying out comparisons are space vector pulse width modulation (SPVPWM), sinusoidal pulse width modulation (SPWM), and third harmonic injection pulse width modulation (THI-PWM) respectively.

Abstract:

The digital implementation of High-Definition Sinusoidal Pulse Width Modulation (HD-SPWM) achieves a higher accuracy and simplifies hardware design. To generate the digital PWM signal a single BRAM(Block Random Access Memory) is used. The memory allocation of the targeted FPGA device is reduced up to 43%. This reduces the number of slices (logic blocks) and LUTs, used for the implementation of HD-SPWM. The switching and sampling frequency for the generation of HD-SPWM are 20 kHz and 4 MHz respectively. The code is written in Verilog HDL and simulated in Modelsim and synthesized in Xilinx ISE. The Switching frequency achieved is 20 kHz respectively.

Abstract:

Nowadays application of advanced power electronic technology enables producing an AC supply with a phase number higher than three-phase. Five-phase voltage source inverters (5ph-VSI) have been used in advanced power electronic drives to improve the reliability of the drive system and to boost the power capability of the converter as well as to their other inherent merits. This paper shows the mathematical analysis and simulation of the third harmonic injection pulse width modulation (THI-PWM) 5ph-VSI connected with inductive load in three scenarios i.e. star, Pentagon and pentacle. The presented THI-PWM technique for 5ph-VSI aims to increase the inverter fundamental voltage and hence to maximize the utilization of the DC bus without causing over-modulation. The simulation results are compared with typical sinusoidal pulse width modulation (SPWM) and the 10-step mode operation. The proposed scheme may be considered as a compromise case between the two reference cases; as low harmonic components compared with 10-step mode operation and a high utilization factor compared with SPWM.

This paper provides theoretical and experimental discussions on the characteristics of the modular multilevel converter (MMC) when phase-shifted carrier sinusoidal pulse-width modulation (PSC-SPWM) is applied. Harmonic-cancellation characteristics of output voltage and circulating current are analyzed on the basis of a general implementation of PSC-SPWM with two freedom displacement angles. Five available PSC-SPWM schemes with different carrier displacement angles were obtained, and a detailed performance comparison about output voltage and circulating current harmonic characteristics is presented. On the basis of the equivalent circuit with ideal transformer representation of the SMs, capacitor voltages affected by PSC-SPWM schemes are also briefly analyzed. The proposed PSC-SPWM schemes can unify two different cases of odd and even SM situations for output voltage and circulating current harmonic minimization, respectively. Lastly, the optimal schemes for practical MMC application were verified by simulation and experiments on an MMC prototype.

Multi-level voltage source converter is integrated in various fields in renewable energy power generation technologies such as wind and solar sources for applications that need higher voltage and higher power. In wind power generation market, doubly fed induction generator (DFIG) based on wind power generation is now the leading technology as they are economically feasible, they do offer a variable speed and efficient substitute to the fossil fuel. This paper proposes a DFIG based on a back to back diode clamped multilevel converter systems (DCMLI) fired comparatively by sinusoidal pulse width modulation (SPWM) and third harmonic injection pulse width modulation (THIPWM) techniques. By using these technologies, the DFIG performance is compared for different wind speeds under normal operation condition. The proposed approach shows that the DCMLI systems generate a near sinusoidal voltage with lower values in total harmonic distortion (THD) thus, upgrading the power quality that is produced by DFIG. Lastly, the variation of frequency of induced rotor voltage and the active power flow due to the wind speed changes when the rotor speed changes from super synchronous to sub synchronous speeds is investigated.

Many high voltage applications require three-phase inverters. The major challenge in inverter designing is the mitigation of harmonic distortion (HD) to achieve better inverting performance. Usually, sinusoidal pulse width modulation (SPWM) is widely used to trigger the inverting switches for controlling the total HD performance in the inverter. To provide the option of multiple operating ranges the multilevel inverters are designed for higher voltage operations. This paper contributes in two passes, first, an improved SPWM modulation is generated for designing the three levels inverter. Then in the second pass, the performance of the THD is evaluated under the different load conditions using V-I measurement. THD is present in the system due to the use of switches. Therefore, this paper has evaluated the performance of the proposed improved SPWM based multilevel inverter for analysis. In order to improve the performance, the modulation index of the SPWM block is varied. The performance of the component report is also presented in the short..the output waveform of the line current and the voltage are compared; The FFT analysis is done to evaluate the comparison of THD performance. It is concluded that improving the SPWM performance and the lording conditions may improve the THD performance also.

This paper presents a proposed modified pulse width modulation – low frequency triangular (MPWM-LFT) switching strategy for minimization of voltage THD with implementation of asymmetric multilevel inverter (AMLI) topology on the reduced number of switching devices (RNSD) circuit structure. Principally, MPWM-LFT able to produce optimum angle of the output voltage level in order to minimize total harmonic distortion (THD). In this study, 5-level reduced number of switching devices circuit structure is selected as a circuit configuration for asymmetric (7-level structure) multilevel inverter. For switching strategy, MPWM used low switching frequency in producing signal and needs higher output voltage levels to achieve low total harmonic distortion. In contrast, sinusoidal pulse width modulation used high switching frequency in order to minimize total harmonic distortion. By optimizing angle at the output voltage using MPWM-LFT switching strategy, the voltage THD is lower as compared to MPWM and SPWM switching strategies. MPWM-LFT switching strategy obtains 11.6% of voltage THD for the 7-level asymmetric topology as compared to MPWM and SPWM switching strategies with the voltage THD are 21.5% and 17.5% respectively from the experimental works.

Abstract:

The present work deals with multilevel inverters (MLI) with modified carrier pulse width modulation technique and its application, especially in solar-based applications due to its modularity in structure and suitability for medium or high-power applications. Several multilevel inverters are introduced for various applications. One of the drawbacks of these inverters is high total harmonic distortion (THD) value in the output which impacts the power quality. The main objective of this work is to improve the power quality, thereby increasing the life and performance of the overall system at the consumer side. The most popular and compact cascaded multilevel DC-link inverter (CMDCLI) is considered for study and employed for 11-level operation. In general, sinusoidal pulse width modulation (SPWM) technique is used for control of inverter. However, the present work proposes a modified carrier-based hybrid pulse width modulation (HPWM) technique and has been tested with CMLDCLI. This novel technique compares the THD performance results with normal carrier wave considering R-L load. The results are analyzed in MATLAB environment and are validated with experimental results.
