Abstract
In this paper, a new non-isolated high gain dc-dc converter based on coupled inductor is introduced. The proposed converter is comprised of two boost converters and two voltage multiplier cells (VMC). In comparison with recently presented ultra high step-up dc-dc converters, the voltage stresses on semiconductors of proposed converter are reduced along with increasing of the voltage gain. In addition, all used MOSFETs in the proposed converter are turned-on under zero voltage and zero current switching (ZVZCS) condition. Moreover, all diodes are turned-off under zero current switching (ZCS) condition. Therefore, the switching loss of presented converter is reduced. These factors are caused the proposed converter become a good choice in comparison with traditional high gain dc-dc converters. The steady-state analysis, design consideration and simulation results of the typical 40V/1100V, 490W, 25kHz converter are given.
