Abstract
The present invention relates to the technical field of high-gain DC-DC converters, and disclosed is a high-gain quasi-resonant DC-DC converter based on a voltage doubling rectifier circuit. On the basis of a half-bridge quasi-resonant high-gain circuit topology and by combining a bidirectional positive and negative voltage doubling rectifier circuit, the present invention provides a high-gain DC-DC converter. The converter can further improve output voltage gain and reduce output voltage ripples, and can improve the system efficiency while reducing the number of turns of a high-frequency transformer; moreover, the converter can achieve soft-switching control, thereby having the advantages of low voltage and current stress, high efficiency, and the like.
