Abstract :
In this paper, an improved KY converter is presented, which is constructed mainly by one charge pump capacitor and one central-tapped coupling inductor. Besides, a passive clamping snubber is added to this converter to improve the efficiency above half load. As compared to the KY converter, the voltage gain of the proposed converter is upgraded significantly. In this paper, the basis operating principles and mathematical deductions of the proposed converter are described, along with some experimental results provided to verify the feasibility and effectiveness of the proposed converter.
