Abstract:
AbstractThe paper presents investigation results of the natural balancing phenomena in the flying-capacitor SEPIC converters. The SEPIC converters topologies can be reconfigured to the flying-capacitor topology. Owing to this modification the advantageous increase of frequency of the current in the chokes and the decrease of semiconductors voltages can be achieved which is shown in this paper. Similarly to other multilevel flying capacitor topologies the adequate voltage sharing of the flying capacitors is an important issue for safe operation of the converter. The paper focuses on the analysis of the flying capacitor voltages balancing in the converter by natural currents as well as by the application of the additional RLC balancing booster. The paper proves that the natural balancing can be achieved by the specific application of the balancing circuit in the flying-capacitor SEPIC topology and proves the specific differences in the balancing process by natural currents of converter and with the usage of the balancing circuit. An operation of the converter with the balancing circuit and the natural balancing ability is studied here.

Abstract:
In this paper, a novel four-level flying capacitor inverter and its comparison with the conventional flying capacitor topology in terms of THD analysis are proposed. This new topology have some advantages over conventional one as following: The blocking voltages are the same for all switches used in the configuration, there is no need for capacitor midpoint connection and this eliminates low frequency current which circulate in dc-link capacitors, and the number of flying capacitor is reduced as compared with conventional form of it. The operation of the topology, modulation strategy, simulation results, and THD analysis for the output waveforms are presented in this paper.Article History: Received: 17th July 2017; Received: October 14th 2017; Accepted: Januari 18th 2018; Available onlineHow to Cite This Article: Gülpınar, F., Sarı, F., and Uzun, Y.

Abstract:
Abstract This paper proposes a novel configuration of conventional flying capacitor (FC) inverter called cell flying capacitor converter (CFC). The proposed topology is obtained by replacing the clamping capacitor of flying capacitor converter with number of series connected half-bridge cells. The main advantages of the proposed converter, compared to the conventional FC converter, are drastic reduction in the number of switches and capacitors. Furthermore, there are redundant switching states which cause to create different pole voltages. In this structure, it is possible to balance the capacitor voltages instantaneously in any direction of the current, by selecting suitable switching states, irrespective of the load power factor. To evaluate performance of the proposed configuration and its control strategy, simulation has been done in MATLAB/Simulink and results have been presented.

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005.
A switching state substitution must be developed that will make use of both single-phase redundancies and three-phase redundancies in the flying-capacitor topology. Losses should be taken into consideration and the algorithm must be designed for implementation on the existing PEC33 system, with on-board DSP (TMS320VC33) and FPGA (EP1K50QC208). The specific power-electronics application is a medium-voltage active filter. Existing capacitor voltage stabilisation schemes are investigated and a capacitor-voltage based algorithm is developed that is investigated in parallel with the Donzel and Bornard algorithm. Detailed simulation models are built for the evaluation of both existing and the proposed algorithm. Three-phase control is also evaluated. Timing analysis of the proposed algorithm shows that a DSP-only implementation of the proposed capacitor-based solution is not feasible. Detail design of the digital controller hereof is implemented in VHDL. Finally, a four-cell controller is fitted into the FPGA. A scalable hardware sorting architecture is utilised.

Abstract:
Voltage and current unbalance are major problems in distribution networks, particularly with the integration of distributed generation systems. One way of mitigating these issues is by injecting negative sequence current into the distribution network using a Static Synchronous Compensator (STATCOM) which normally also regulates the voltage and power factor. The benefits of modularity and scalability offered by Modular Multilevel Cascaded Converters (MMCC) make them suitable for STATCOM application. A number of different types of MMCC may be used, classified according to the sub-module circuit topology used. Their performance features and operational ranges for unbalanced load compensation are evaluated and quantified in this research. This thesis investigates the use of both single star and single delta configured five-level Flying Capacitor (FC) converter MMCC based STATCOMs for unbalanced load compensation. A detailed study is carried out to compare this type of sub-module with several other types namely: half bridge, 3-L H-bridge and 3-L FC half bridge, and reveals the one best suited to STATCOM operation. With the choice of 5-L FC H-bridge as the sub-module for STATCOM operation, a detailed investigation is also performed to decide which pulse width modulation technique is the best. This was based on the assessment of total harmonic distortion, power loss, sub-module switch utilization and natural balancing of inner flying capacitors. Two new modulation techniques of swapped-carrier PWM (SC-PWM) along with phase disposed and phase shifted PWM (PS-PWM) are analyzed under these four performance metrics. A novel contribution of this research is the development of a new space vector modulation technique using an overlapping hexagon technique. This space vector strategy offers benefits of eliminating control complexity and improving waveform quality, unlike the case of multilevel space vector technique. The simulation and experimental results show that this method provides superior performance and is applicable for other MMCC sub-modules. Another contribution is the analysis and quantification of operating ranges of both single star and delta MMCCs in rating the cluster dc-link voltage (star) and current (delta) for unbalanced load compensation. A novel method of extending the operating capabilities of both configurations uses a third harmonic injection method. An experimental investigation validates the operating range extension compared to the pure sinusoidal zero sequence voltage and current injection. Also, the superiority of the single delta configured MMCC for unbalanced loading compensation is validated.

Abstract:
Voltage fluctuation and power losses in the distribution line are problems in distribution networks. One method to mitigate these problems is by injecting reactive power into the network using a Static Synchronous Compensator (STATCOM). This can be used both for regulating the voltage and reducing the losses. A STATCOM is critically dependent on a grid synchronisation scheme that can accurately track the changes occurring in the grid phase and frequency. The Modular Multilevel Converter (MMC) is a promising topology for STATCOM applications because of its simple modular circuit structure that allows for higher voltage ratings, and conventionally uses a stack of sub-modules which are either two-level half or H-bridge converters. As a novel alternative, the thesis investigates the practicality of a STATCOM based on a three-level flying capacitor (FC) converter. Two variants of this topology are presented; the FC Half-bridge and FC H-bridge. A comprehensive study is undertaken to compare these with the Half and H-bridge sub-module under STATCOM operation. Most importantly, an FC H-bridge-based STATCOM is investigated for reactive power compensation. The challenges of multilevel, multi-module PWM control schemes achieving good waveforms at low switching frequency, whilst maintaining module capacitor voltage balance, are thoroughly addressed. Simulation results validate the operation for both line voltage regulation and power factor correction. An experimental power system with an FC-based STATCOM rig is designed and built, and validates the simulation results for power factor correction. It demonstrates correct operation of a control scheme that includes a system for maintaining capacitor voltage balance. Another new contribution is the investigation of a phase locking technique based on the Energy Operator (EO). The method, combining two different EO computations, is shown to achieve fast and accurate detection of frequency and phase angle when combined with an appropriate filter, and crucially operates well under unbalanced voltage conditions. The technique is compared with two other well-known phase locked loop (PLL) schemes, showing that it outperforms the others in terms of speed and accuracy. A hardware implementation of the EO-PLL validates the principle, showing the simplicity of the method.

Abstract:
Widespread growth of the consumer electronics market and the upward trend in harnessing electrical power from renewable sources has increased the number of power electronic converters connected to utility distribution systems. Power electronic converters offer flexibility in voltage and current control as well as improved energy efficiency, but generate harmonic currents which have detrimental effects on the power system. A particular challenge appears in 4-wire networks where zero-sequence harmonics exist; such currents accumulate in the neutral conductor and pose threats of overheating and failure. This work investigates harmonic compensation using shunt active power filters with specific application to unbalanced distribution networks. Owing to its increased availabil- ity of switching states, the flying-capacitor multi-level inverter (FCMI) is explored; how- ever an additional challenge exists in the balancing of capacitor voltages. Furthermore, synthesis of unbalanced inverter output volt ages necessitates a three-dimensional pulse- width-modulation (3D-PWM) strategy. This work proposes a new modulation scheme, specifically suited to 4-limb FCMIs, which combines 3D-PWM and natural flying-capacitor voltage control. To develop an optimal harmonic compensation strategy, it is important to understand the nature of harmonic distortion experienced in typical distribution systems. New data on harmonics generated by common single-phase appliances are presented and a compre- hensive power-quality study is performed on a typical 4-wire network. Findings are used to develop a computer model which emulates realistic harmonic load current waveforms. The final contribution in this work lies in the development of an unbalanced harmonic extraction technique based on synchronous reference frame theory and a new modified deadbeat controller which compensates delays and improves reference current tracking. In conjunction with the proposed 3D-PWM scheme, the complete control strategy pro- vides compensation of positive, negative and zero-sequence harmonic currents in addition to alleviating phase load imbalance. A bespoke FCMI test rig is developed, providing experimental validation of the proposed system.

Abstract:
Two vital and dynamically changing issues are arising in the electric grid - an increase in electrical power demand, and subsequent reduction in power quality. Power electronics based solutions such as the Static Synchronous Compensator are increasingly deployed to mitigate power quality issues while High Voltage DC Transmission converters are currently installed to support the existing grid transmission capacity. Both applications require high power and high voltage power converters using switching devices with limited voltage ratings. The advent of Modular Multilevel Converters (MMC) is one of the recent responses to this need. These use half or full H-bridge circuits stacked up to form a chain, and hence can withstand high voltages using lower-rated switching devices. This thesis introduces a new member into the MMC family, i.e the Modular Multi-level Flying Capacitor Converter (MMFCC). This uses a three-level flying capacitor full-bridge circuit as a sub-module and offers features of modularity, scalability and fault tolerance. The choice of FC topology in place of the simple H-bridge stems from the FC’s ability to offer two extra voltage levels in the sub-module output and hence more degrees of freedom per module in controlling the voltage waveform. A three-level full-bridge FC sub-module uses three capacitors - an outer one for supporting the sub-module voltage, and two inner floating ones with half of the outer one’s capacitance and voltage rating. This use of slightly more complex FC sub-modules gives the benefits of a modular structure but without using twice as many sub-modules with their associated capacitors for the same total voltage. The thesis presents the principles of this topology, switching states redundancies and a method for capacitor voltage balancing. Also discussed are: the configuration of MMCC including the MMFCC in Single-Star Bridge-Cell (SSBC) or Single-Delta Bridge-Cell (SDBC) for FACTS and Battery Energy Storage System (BESS) applications; and Double-Star Chopper-Cell (DSCC) or Double-Star Bridge-Cell (DSBC) for HVDC systems. A novel overlapping hexagon pulse width modulation scheme is introduced and discussed for switching control of the MMFCC. This uses multiple hexagons all centred on one point, the same in number as the cascaded FC sub-modules, which are phase displaced relative to each other. The approach simplifies the modulation algorithm and brings flexibility in shaping the output voltage waveforms for different applications. An MMFCC experimental rig was designed and built in-house to validate some of the simulation results obtained for the modulation of this new topology. Details of the rig as well as results captured are discussed.

ENGLISH ABSTRACT: This thesis investigates the viability of constructing a solid-state transformer (SST) with a series-input, parallel-output connection of full-bridge, three-level ying-capacitor converters. It focusses on the active recti er front-end of the SST which is used to control the input current to be sinusoidal and in-phase with the sinusoidal input voltage. A stack of two converters are built and tested. The input current, as well as the ying capacitor voltages of the two active recti ers in the stack, are actively controlled by a nite-state model-based predictive (FS-MPC) controller. The use of multiple ying-capacitor converters poses a problem when using FS-MPC because of the large number of possible switching states to include in the prediction equations. Three FS-MPC control algorithms are proposed to attempt to overcome the problem associated with the large number of switching states. They are implemented on an FPGA digital controller. The algorithms are compared on the bases of voltage and current errors, as well as their responses to disturbances that are introduced into the system. The simulation and experimental results that are presented shows that by interleaving the control actions for the two converters, one can obtain fast and robust responses of the controlled variables. The viability of extending the interleaving control algorithm beyond two converters is also motivated.
AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die moontlikheid van volbrug, drievlak vlieënde-kapasitoromsetters wat gebruik word om 'n serie-intree, parallel-uittree drywingselektroniese transformator (DET) te bou. Dit fokus op die aktiewe gelykrigter van die DET wat gebruik word om die intreestroom te beheer om sinusvormig en in fase met die sinusvormige intreespanning te wees. 'n Stapel van twee omsetters word gebou en getoets. Die intreestroom, sowel as die vlieënde kapasitorspannings van die twee aktiewe gelykrigters in die stapel, word aktief beheer met behulp van 'n eindige-toestand, model-gebaseerde voorspellende beheerder (ET-MVB). Die gebruik van veelvuldige vlieënde-kapasitoromsetters bemoeilik die implementering van 'n ET-MVB-beheerder as gevolg van die groot aantal skakeltoestande wat in die voorspellende vergelykings in ag geneem moet word. Drie ET-MVB-algoritmes word voorgestel om te poog om die probleme, wat met die groot aantal skakeltoestande geassosieer word, te oorkom. Die algoritmes word in 'n FPGA digitale verwerker geïmplementeer. Die algoritmes word vergelyk op grond van hul stroom- en spanningsfoute, asook hul reaksie op steurings wat op die stelsel ingevoer word. Die simulasie en praktiese resultate toon dat, deur die beheeraksies vir die twee omsetters te laat oorvleuel, die gedrag van die beheerde veranderlikes vinniger en meer robuust is. Die moontlikheid om die oorvleuelende beheeraksies uit te brei tot meer as twee omsetters word ook gemotiveer.

Abstract:
This dissertation presents voltage stabilization techniques for flying capacitors used in soft-switching multilevel active power filters. The proposed active filter has proved to be a solution for power system harmonics produced by static high power converters. However, voltage unbalance of the clamping capacitors in the active filter in practical applications was observed due to its unequal parameters. Thus, the fundamentals of flying capacitors were characterized dealing with voltage balancing between flying capacitors and dc capacitors under practical operation, rather than ideal conditions. The study of voltage balancing provides the fundamental high-level solutions to flying capacitor based multilevel converter and inverter applications without additional passive balancing circuits. The use of proposed voltage balancing techniques made it possible to have a simple structure for solving the problems associated with the conventional bulky passive resistors and capacitor banks. Furthermore, the proposed control algorithms can be implemented with a real time digital signal processor. It can achieve the high performance of the active filter by compensating an adaptive gain to the controller. The effectiveness of the proposed controller was confirmed through various simulations and experiments. The focus of this study is to identify and develop voltage stabilization techniques for flying capacitors used in a proposed active filter. The voltage unbalance is investigated and characterized to provide safe operations. After having defined the problems associated with the voltage unbalance, the most important voltage stabilization techniques are proposed to solve this problem, in conjunction with an instantaneous reactive power (IRP) control of an active filter. In order to reduce the switching losses and improve the efficiency of the active filter, the proposed soft-switching techniques were evaluated through simulation and experimentation. Experimental results indicate that the proposed active filter achieved zero-voltage conditions in all of the main switches and zero-current turn-off conditions to the auxiliary switches during commutation processes. Also, various studies on soft-switching techniques, multilevel inverters, control issues and dynamics of the proposed active filter are discussed and analyzed in depth.
