   5-Level Double-Boost PFC with Fault-Tolerant Capability

[Download]

Abstract: A new 5-level non-differential PFC topology with fault tolerant capability is presented and compared to known structures. It is derived from a 3-level double-boost PFC. The series-connection of the two low-voltage switching-cells decoupled by a single flying capacitor provides a fault-tolerant capability and a post failure operation increasing the availability of converter. The most important features are highlighted. Moreover, a AC115V â€“ DC400V - 4kW â€“ 2 x 48kHz mock-up was built to validated studies. A preliminary analysis is also presented on the physical / electrical failure mode of a 600V/60A CoolMosâ„¢ taking into account the post-failure stability from a series redundancy standpoint.

   Analysis of Current Characteristics of Parallel Three-Phase Voltage Source Inverters

Abstract: The current characteristics of two types of parallel three-phase voltage source inverter configurations are analyzed, and the suitability of different pulse width modulation methods in the control of parallel inverters is discussed. The analysis and discussion are based on state-space models derived in this paper and presented for the parallel connection of n units. For the sake of repeatability, a systematic derivation procedure applying Luenberger's shuffle algorithm is also presented. The main purpose of the current characteristics analysis is to highlight the major differences between the considered parallel inverter configurations. Thus, the analysis is basically a circulating current characteristics analysis. The suitability of sinusoidal PWM, space vector PWM, and 60 degree discontinuous modulation in the control of parallel inverters is studied by simulations. The purpose of the simulations is also to illustrate the differences between the parallel inverter configurations in practice.

   Comparison between Different Shoot-Through PWM Control Methods for Different Voltage Type Z-Source Inverter Topologies

Abstract: In this paper, four PWM control methods: simple boost, maximum boost, maximum constant boost, and modified space vector PWM control are reviewed and compared for different voltage type Impedance Source Inverter (ZSI) topologies. There are three different topologies for three phase-two level-voltage type ZSI: basic, bidirectional, and high performance ZSI. For purposes of comparison, these three ZSI topologies are simulated by using the different four PWM control methods for the same input voltage, shoot-through duty ratio, peak dc voltage across the inverter, switching frequency and output load. These simulations have been developed in Simulink/Matlab for a 30 kW ZSI designed for hybrid electric vehicle applications. The comparison shows that the maximum constant boost control is the most suitable PWM control method for all ZSI topologies. Also, the paper presents a review for optimal impedance network parameters design.
