一种具有高电压增益和全范围ZVS的新型交错式非隔离双向DC-DC变换器

A nonisolated soft-switching bidirectional dc-dc converter (BDC) with interleaved technique and built-in transformer (BT) is proposed for the interface between the energy storage system and dc microgrid bus in this article. A T-type neutral-point-clamped circuit is integrated into an interleaved conventional buck-boost BDC to obtain a high voltage-gain ratio and decrease voltage stresses of power ...
