具有宽电压增益和全范围ZVS的双极性直流微电网自动电压平衡DC-DC变换器

In order to balance the bipolar dc voltage and avoid dc bias for high-frequency transformer under unbalanced load conditions, a bipolar dc–dc converter is proposed. With the balanced inductor, it can be guaranteed to achieve automatic voltage-balancing under any load conditions, without additional voltage-balancing control. While with the inserted blocking capacitor on the secondary side, the dc b...
