一种采用扩展占空比控制和磁集成电感的电流型双有源桥DC-DC变换器及其优化电压失配控制

For a current-fed dual-active-bridge bidirectional dc-dc converter, an extended duty cycle control is proposed. The low-voltage-side (LVS) bottom switch duty cycle can operate lower than 50%. The conduction loss of switches can be reduced by using low-voltage-rating mosfets for the LVS. Meanwhile, a voltage mismatching control with adaptive clamp voltage regulation is proposed to achieve zero-volt...
