基于功率器件电流平衡的全桥三电平DC/DC变换器调制策略

This paper proposes a new modulation strategy with balanced power device currents for the full-bridge three-level dc/dc converter. The proposed modulation strategy has two working patterns, which cannot only realize zero-voltage switching (ZVS) but also satisfy the wide input voltage range. More significantly, the two working patterns of the proposed strategy can balance the currents both among th...
