电流型双有源桥DC-DC变换器的变开关频率控制与恒磁通密度变化研究

For current-fed dual-active bridge bidirectional dc-dc converters, a PWM plus dual phase shifted (PPDPS) control with varying switching frequency was proposed. To prevent magnetic core saturation, the flux density change of the transformer is kept constant in spite of the battery voltage and the load. The detailed loss breakdown was implemented by comparing with the conventional PPDPS with fixed s...
