摘要
该文提出了一种PWM加相移控制的双向DC/DC变换器。该变换器结合了PWM和相移这两种控制技术优点,不但可以减小变换器的电流应力和通态损耗,而且可以拓宽零电压开关的范围。该文详细地介绍和分析了变换器的工作原理,给出零电压开关的条件,最后给出了实验结果。
A PWM plus phase-shift control bidirectional DC/DC converter is proposed. In this converter, PWM control and phase-shift control are combined to reduce current stress and both conducting and switching loss, to expand ZVS range. The operation principle and analysis of the converter are explained, and ZVS condition is derived. A prototype of PWM plus phase-shift bidirectional DC/DC converter is built to verify analysis.
