具有改进ZVS范围且无变压器饱和问题的隔离型双降压DC-DC变换器

In this paper, an isolated double step-down dc-dc converter with high efficiency and high step-down function is proposed. The proposed converter employs an additional capacitor in the primary side. Compared to the conventional full-bridge converters, the proposed converter has a double step-down feature with reduced voltage stress at the primary side of the transformer. Moreover, voltage stress of...
