摘要：
This study proposes a non-isolated high gain DC-DC converter. The introduced topology is combination of boost and sepic converters. In comparison to proposed converters in literature, it has been tried to reduce stresses of semi conductor devices. Diodes and switches of introduced topology operate asynchronously. Positive polarity of proposed converter have caused same ground for load and input source. Voltage ratio of proposed converter is multiplication of conventional boost and buck-boost converter voltage gains. Design parameters, mathematical relations of efficiency and small signal analysis have been done for proposed converter in Continuous Conduction Mode. At the end, simulation results of proposed converter have been reported and correctness of expressed relations have been proved.
