基于二次型升压变换器和开关电容的混合式升压方案研究
Hybrid Boost Scheme Based on Quadratic Boost Converter and Switched Capacitor
摘要
Abstract
A hybrid high boost ratio DC-DC converter is proposed,which consists of a secondary boost converter,a switched capacitor and a coupled inductor unit integrated.In order to reduce the number of components,the primary side of the coupled inductor is shared with the secondary boost converter.The output capacitor of the secondary boost converter is divided into two and shared with the switc-hing capacitor.Due to the topology of common ground between source and load,the input source current is continuous.The voltage gain of the proposed converter is derived and its voltage stress is analysed.The results show that the proposed inverter has a high voltage gain and low voltage stress.Finally,an experimental prototype of 80 W is built and the experimental results verify the correctness and effec-tiveness of the proposed converter.关键词
