Optimum Design of Energy Transfer Inductor in Phase-shifted Bidirectional Converters

提出了一种相移控制双向DC/DC变换器中能量传输电感的设计方法。通过这种设计方法,可使变换器在一定输出电压范围内平均电流应力最小,并且使变换器在一定输出电压范围内基本实现软开关。详细介绍和分析了能量传输电感的设计方法,给出了实验结果。

A novel method for designing the energy transfer inductor in phaseshifted bidirectional converters is presented.Average current stress is minimized in a range of output voltage,and the converter can achieve ZVS in the range of output voltage.A prototype of phaseshifted DC/DC bidirectional converter is built to verify the analysis.
