一种具有ZVS运行和低开关电压应力的非隔离超高升压二次型变换器

This article proposes a nonisolated quadratic converter with ultra-high voltage conversion ratio. In the presented structure, an auxiliary circuit containing coupled inductors (CIs) and a voltage multiplier cell is integrated with the quadratic converter to obtain higher voltage gain. As a result, voltage stress over switches is reduced significantly and mosfets with low on-resistance can be used ...
