双开关二次型结构的耦合电感高增益DC-DC变换器
Dual-switch Quadratic High-gain DC-DC Converter with Coupled Inductor
摘要
Abstract
Under the background of energy crisis and environmental issues,the high-gain DC-DC converter is indispensable in renewable energy applications.A dual-switch quadratic structure is proposed to enhance the voltage gain of the traditional quadratic boost converter while reducing the current stress of switches.On this basis,by combining the switched capacitors and a coupled inductor,a dual-switch quadratic high-gain DC-DC converter with a couple inductor is put forward.This converter has advantages such as a very high voltage gain,a pair of switches with the same phase,low voltage stress of switches and output diode,and zero-current switching off in many diodes.The operating principle and steady-state performance of the converter are analyzed in detail,including the voltage gain derivation and the voltage and current stresses of components.Finally,a 120 W prototype was fabricated to verify the theoretical analysis and the feasibility of the converter.关键词
