一种适合18脉波整流的新型DC/DC变换器
A New Type of DC/DC Converter Available for 18-pulse-waveform Rectifier
摘要
Abstract
Multiple phase rectification techniques are used in 18-pulse-waveform rectifier with autotransformer mode to improve the power level and lower the harmonics of the devices, while the used phase-shift autotransformer can reduce the volume, weight and cost of rectifier, but not to implement the electric isolation. Therefore, by combining the multiple pulse rectifier with the implementation of DC/DC converter soft switching, this paper proposes the strategies of using the full-bridge phase-shift in the primary and a novel DC/DC converter configuration with multiple rectifier in the secondary, next, analyses the operating principles of soft switching, and finally, performs the corresponding simulation and experiment. Simulation results show that the theoretical analysis is correct, and the designed converter can realize the zero-voltage on and off of lagging bridge arm switching transistor.关键词
