High voltage gain dc-dc converters are widely using in solar systems, fuel cell and automobile electronic lamp ballast. The voltage gain of the classic converters is limited considering the issues such as the high voltage stress on the switch and diode and low efficiency and because of this issues, high voltage gain dc-dc converter must be used. In this paper, a new high step up dc-dc converter based on KY converter is proposed. The proposed converter achieves high voltage gain with appropriate duty cycle. The proposed converter has low voltage stress on the active switch, which makes reducing the switching power loss. The operation modes of the proposed converter and the steady-state analyses of are presented in detail. To verify the operation of the proposed converter, simulation results in PSCAD/EMTDC software are provided.
