| 摘 要： | 文中主要研究的对象是开环控制的交错并联BOOST PFC,且工作于临界续断模式,它的从变换器与主变换器在开通时同步,且主从变换器都工作在电流模式。文章指出只有这种主从方式能提供一个稳定的开环工作点。仿真实验设计了一台输入功率为400W,宽范围输入电压,400V输出电压的实验样机,实验结果验证了理论分析的正确性。

| Abstract: | This paper is focused on the interleaved DCM/CCM boundary boost PFC converters based on the open-loop control.The slave converter is synchronized to the master converter and both of the converters operated in current-mode control.It's shown that it is the only open-loop control method that can provide a stable operation.Finally a 400 W,universal input,400 V output prototype circuit is designed.Experimental results prove the Boost PFC is effective and it can achieve stable output voltage with high input powe... |
