Power electronic converters use power semiconductor devices and other passive elements to convert electrical energy from the form supplied by a source to the form required by a load. The proposed system describe the multi-input dc–dc/ac boost converter. The input source can be regulated by using the single power switch of each unidirectional boost converter. The output reference voltages can be produce with the help of the converter central part both upper and lower power switches of the bidirectional boost converters which are complementary switched. The dc-dc and dc-ac conversion is the process for change the multiple DC outputs in required output forms like AC or DC values. It helps to give DC are AC voltage for desired load. That convertor used to hybrid of multi DC inputs and give the required DC or AC outputs. In our proposed we create a new topology for DC-AC/DC converters by using the IGBT diodes and Fuzzy logic controller. In our desired output will improve the better output quality.
