基于开关电感的混合二次型Boost DC/DC变换器
A hybrid quadratic boost DC/DC converter based on switched-inductor structure
摘要
Abstract
Photovoltaics and fuel cells application fields put forward higher requirement on the voltage gain for the boost DC/DC converter.Aiming at the problem of inadequate boost ability of traditional boost DC/DC converter,this paper proposed the hybrid quadratic boost converter by combining with the advantages of the switched-inductor structures to raise the voltage gain of the boost converter,which is based on the quadratic boost converter.According to the different values of the inductor L1 and L2 among switched-inductor structures,the operation principle of the hybrid quadratic boost DC/DC converter is analyzed under condition of L1＞L2,L1=L2 and L1＜L2 in detail.Compared with the conventional quadratic Boost Converter,the voltage gain of the hybrid quadratic boost converter is higher and the input inductor value is smaller.Based on the theoretical study,a test prototype was built and the experimental results were given to verify the validity of the proposed converter.关键词
