A novel high voltage gain DC-DC converter with reduced components voltage stress

In this paper a novel high step up single switch dc-dc converter with high efficiency is proposed. In this converter, high voltage gain is achieved using coupled inductor and diode capacitor techniques. Hence, there is no need to use extreme duty cycle. Moreover, the output diode reverse recovery problem has been alleviated in the proposed converter. The voltage stress across all circuit elements has been reduced which decreases the overall size and cost of the proposed converter. Operation principles and steady state analysis of the proposed topology are discussed in detail. Finally, some simulations have been done to verify mathematical derivations and mentioned features of the proposed converter.
