| Abstract: | The high step-up Boost converter based on topology combination is proposed in this paper.The operation principle and property of the converter are analyzed in detail.The experimental results are given.When duty ratio D>0.5,the converter has these characteristics as follows: Firstly,the voltage gain is double of the basic Boost converter.Secondly,the two Boost cell of the converter can realize current sharing automatically,which is unlike the interleaved Boost converter,and therefore,the control circuit is simple.Finally,the voltage stress of the active switch is half of the output voltage,namely,it is half of the voltage stress of the basic Boost converter. |
