Abstract

A DC-DC converter with large step-down voltage conversion is presented in this paper. The proposed converter integrates a DC-DC buck converter with a hybrid DC-DC step-down converter by using a single switch to achieve large step-down voltage conversion. The rear semistage employs a coupled inductor with same winding turns in the primary and secondary sides. The primary and secondary windings of the coupled inductor are operated in series during ON-period and are operated in parallel during OFF-period. Also, the operating principle and steady-state analysis is discussed. Finally, the simulation results are shown to verify the performance of the proposed converter.
