Abstract:

Power electronic converters are in the heart of modern renewable energy and motor drive systems. This Thesis focuses on the converter dc-link capacitor (bank), which is a costly component and a common source of failures. The Thesis is divided into two parts. The first part examines the voltage and current stress induced on dc-link capacitors by the three most common converter topologies: The conventional two-level converter, the Neutral-Point-Clamped (NPC) three-level converter, and the Cascaded H-Bridge (CHB) three-level converter. The expressions derived for the rms capacitor current and its

Abstract:

AC/DC adapters mostly employ two-stage topology: Power Factor Correction (PFC) pre-regulation stage followed by an isolated DC/DC converter stage. Low power AC/DC adapters require a small size to be competitive. Among their components, the bulk DC-link capacitor is one of the largest because it should keep the output voltage with low ripple. Also, the size of this capacitor is penalized due to the universal line voltage application. Synchronization through employing leading edge modulation for the first PFC stage and trailing edge modulation for the second DC/DC converter stage can significant

Abstract:

Multi-pulse converters have been widely used for a multi-megawatt scale power generating system to comply with harmonic regulations. Among all types of multi-pulse converters, a 12-pulse converter is the most widely used due to the simple structure, which consists of a delta-delta and a delta-wye phase-shift transformer pair and it effectively mitigates undesirable harmonics from the nonlinear load. In the early 2000s, a shunt type passive front-end for a shipboard power system was proposed. By shunting the two gensets with 30° phase angle difference, a single phase-shift transformer effecti

Abstract:

Switch mode auxiliary circuits have been used to balance the de-link capacitor voltages of a diode-clamped five-level inverter. The use of the smps has been extended to charge- lip and discharge the four de-link capacitors. Complete diode-clamped five-level inverter operation has been implemented from inverter start-up, to link charge-up, to balanced pwm operation, to de-link discharge, and shut-down. The diode-clamped smps is used to charge and boost the two lower de-link capacitors simultaneously. Auxiliary circuit and boost converter duty cycles are used to control the de-link charge-up and

The AC-DC-AC converter consists of an AC-DC active front-end converter, a DC-AC voltage source inverter, and a 20uF ceramic capacitor in DC link. The DC bus voltage controller with load compensator is utilized to maintain the voltage of the DC link capacitor at designed value. Furthermore, the multi-carrier PWM is utilized to reduce the common-mode voltage (CMV) of AC-DC active front-end converter and DC-AC inverter. The simu

The influence of these PWM strategies on the DC-link capacitor current and voltage ripple is studied in this thesis.

Abstract:

Use of multilevel inverters are inevitable in medium and high voltage drives. This is due to the fact that the multilevel inverters can produce voltages in smaller steps which will reduce the harmonic content and result in more sinusoidal voltages and currents as compared to voltages and currents from two-level inverters. Due to the device limitations, use of two-level inverters is not possible in medium and high voltage drive applications. Though multiple devices can be connected both in series and parallel to achieve two-level operation, the output voltages still suﬀer from high harmonic con

The traditional, regulated electric power systems are based on large power generation plants located far from load centers. In a deregulated market, however, small and environmentally friendly power plants using wind power, photovoltaic cells, fuel cells and micro-turbines can be installed through a given distribution system. This concept of distributed generation tends to reduce the cost of electricity and to reduce or postpone major investments in the transmission system. Many of these small power plants are typically consumer owned and are connected to the utility grid by means of single-p

Abstract:

Grid integration of photovoltaic (PV) energy sources has been mostly governed by conventional two-level voltage source inverters. These topologies have significant switching power losses, dV/dt stress and THD level at lower switching frequencies. The above issues can be solved by introducing more voltage levels through multilevel converters. Conventional multilevel converters have many issues like neutral point voltage drift in neutral point clamped (NPC) topology, floating capacitor charge balance in flying capacitor (FC) topology and large number of isolated DC sources in cascaded half bridg

Abstract:

For low and medium power applications, conventional two-level inverters are widely used in industrial applications including electric vehicle drives, traction drives, distributed generation, power management and grid connected renewable energy systems. To filter out the harmonic currents from the load, passive line filters are used. These filters are designed to pass the fundamental phase current and suppress higher harmonic currents, making the filters bulky. To get a nearly sinusoidal current waveform, these two level inverters are switched at high frequency to shift the harmonic components
