Abstract

In this paper, an ultra-step-up DC-DC converter using a three-winding coupled inductor and a voltage multiplier cell are proposed to achieve high step-up voltage. The important advantages of the proposed converter are as: Only one active switch is required without extreme duty cycle that high voltage is attained, The voltage stress on the active switch and diodes are reduced by increasing the turns ratio of the secondary windings of the coupled inductor, and the energy of the leakage inductance of the coupled inductor is recycled by switched capacitor and directly transfers to the load. The operation principle and steady state analysis of continuous conduction mode are used to determine voltage gain and switch voltage stress. Also the extension of the proposed converter to attain more step-up voltage gain are presented. The simulation results are used to verify the performance and validity.
