This paper presents a power convertor design of a 60kW three-phase asymmetry half-bridge power convertor for switched reluctance machines (SRM). With established topology, voltage overshoot is sufficiently analyzed theoretically. To minimize voltage overshoot, this paper optimized the structure of main circuits, snubber capacitors and drive circuits. When dealing with main circuits structure, a low...
This paper presents a loss calculation method based on the selection of IGBTs and Diodes, and on an analysis of conduction and switching losses in multilevel pulse width modulation (PWM) systems. A comparison between the Modular Multilevel Converter (MMC) and other multilevel topologies, adapted to medium voltage applications, will thus be presented in order to highlight issues such as thermal disparity...
Repetitive pulsed power generation by compact sources is being studied for industrial applications. The research efforts include pulse-compression concept exploration, electrical circuit design and optimization, switching device development and evaluation, and application demonstrations. The basic strategy is to take advantage of solid-state switching devices to achieve compactness, reliability, and...
