双半桥双向DC-DC变换器的解耦PWM加移相控制

This paper presents the analysis of low leakage inductance current regions, small-signal model, and decoupled control for a dual-half-bridge isolated bidirectional dc-dc converter with pulse width modulation plus phase-shift strategy. Traditionally, the duty cycle of the transistors is fixed at 0.5 and only the phase-shift is varied to regulate the output voltage. With PPS control, two control fre...
