In this paper, a novel high voltage gain DC-DC converter based on coupled inductor and voltage multipliertechnique is proposed. The benefits of the proposed converter are ultra-high voltage gain, low voltage stress acrossthe power switch and very low input current ripple by employing a low current ripple structure (LCR) at the inputside. A low on state resistance (RDS(on)) of the power switch can be employed since the voltage stress is a maximum of25% of the output voltage and the conduction losses of the switch is also reduced. Design of a 1.9kW, 48V at the lowvoltage side and 430V at the high voltage side is done and verified by simulation. Simulation results show anefficiency of over 93% when operating in continuous conduction mode (CCM).
