用于光伏微逆变器的带缓冲电容准谐振升压半桥DC-DC变换器

This paper proposes a quasi-resonant boost half-bridge dc-dc converter with high power conversion efficiency and a wide input voltage range for a photovoltaic micro-inverter. The proposed converter has a combined structure of a boost-integrated half-bridge converter on the primary side of the transformer and a voltage doubler with a snubber capacitor on the secondary side. By using the quasi-reson...
