电流馈电半双有源桥DC-DC变换器的优化混合控制

This article proposes a variable clamp voltage control strategy for the current-fed semi dual-active-bridge dc–dc converter. For the low-voltage-side, the duty cycle of the bottom switches will be changed with the load variation. Full-load operation stability and full range of zero-voltage switching (ZVS) can be achieved. An instantaneous turn-off current tracking loop is designed to achieve duty ...
