This paper proposes the novel three phase non isolated high voltage gain boost converter using coupled inductor. The proposed converter consists of coupled inductor based three phase switch cell network, voltage multiplier cell. The high voltage gain is obtained by recycling stored energy in inductor and voltage multiplier cell. The reduced current stress of main switch was obtained by this proposed three phase configuration. Hence conduction loss of three phase boost converter reduced compared to other conventional boost converter. The voltage stress across the switch is reduced by introduction of voltage multiplier at output. This novel three phase configuration reduce input current ripple by use of three phases at input side. The detailed analysis of proposed three phase interleaved boost converter was done by using simulation MATLAB/simulink simulation. The simulation results are presented to analyze the performance parameters of proposed converter.
