具有自动电压平衡和全范围ZVS的双极性电流型DC-DC变换器

The bipolar dc microgrid is attracting attention for its high efficiency and reliability, but the bipolar dc bus is susceptible to unbalanced power. This article proposes a bipolar current-fed dc–dc converter with automatic voltage balance under phase-shift plus pulsewidth control. Combined with the current-fed dual active bridge converter and voltage balancer, the circuit structure is streamlined...
