Abstract

A high step-up dc-dc converter is proposed in this article. With magnetic-coupling-based voltage multiplier technique, the proposed converter achieves high voltage gain and low switch voltage stress. Also, due to a boost inductor at the input, continuous input current is obtained, which is beneficial for battery, fuel cell, and photovoltaic applications. Moreover, zero voltage switching of the mosfets is achieved, leading to low switching losses. Furthermore, zero dc bias of the coupled inductor is realized, resulting in small magnetic size and low core losses. The operation principles, performance analysis, and design considerations of the proposed converter are discussed. A prototype with 40-V input and 400-V output has been developed to verify the theoretical analysis.
