单级交错式图腾柱LLC AC-DC变换器输入输出功率解耦的混合控制策略

This article proposes a hybrid control strategy for a single-stage interleaved totem-pole LLC ac–dc converter. Because the totem-pole power factor correction front cell provides bidirectional inductor current, this converter is restricted by operating in continuous conduction mode or critical conduction mode. The traditional control strategy shows a variable duty cycle of the resonant tank voltage...
