通过优化开关模式实现全负载范围内ZVS的高效率电流型双有源桥DC-DC变换器

For current-fed dual active bridge bidirectional dc-dc converters, all the possible switching patterns are summarized in view of the combinations of both side pulse-width modulation duty cycles and phase-shift angle. A control strategy is proposed for the current-fed dual active bridge converter to operate with the optimized patterns. The equivalent duty cycle of the secondary side is smaller than...
