摘要
介绍了一种采用辅助谐振网络的移相全桥ZVS-PWM变换器,简述其工作原理。使用TMS320LF2407A作为主控芯片,实现了数字移相控制及全桥变换零电压软开关。试制了一台8kW/20kHz的样机,给出了实验波形及结论。
The operating principle of a PS FB （phase-shifted full-bridge） ZVS-PWM converter with auxiliary resonant network are introduced. A digital control system using TMS320LF2407A as the main control chip was designed to achieve digital PS control algorithm, as well as ZVS for IGBT, An 8kW/20kHz prototype was designed, The experimental waveforms and conclusions are provided.
