Abstract : In this paper an efficient single phase step up converter is used to boost the voltage obtained from PV cells. It also provides neutral point terminal to the half bridge inverters. Here, two high steps up converters which are symmetrical are combined to get an efficient converter with neutral point terminal. Also, the voltage gain of the converter is enhanced. By using coupled inductor multiplier narrow turn-off period is avoided and the voltage stress is reduced. Switching losses are reduced because switches act in zero-voltage-switching condition. The simulation results are presented in this paper.
