利用1:1变压器提升AC-DC升压变换器功率转换效率

This paper proposes a circuit structure that can improve the power-conversion efficiency ηe of an AC-DC boost converter. The circuit uses a 1:1 transformer and a voltage boost circuit composed of an inductor, a capacitor, and a diode. The transformer forces the converter to operate in continuous conduction mode for input current, and thereby reduces input ripple. The voltage boost circuit enables ...
