In this paper, proposed circuit proposes that Active-Clamp-Circuits basis of a current-fed inverter linked type high frequency resonant dc-dc converter of conventional. And the paper the most of characteristics of the reduced high voltage stress main switches with active clamp circuits and output current constant with the resonant part consists of L, C resonant tank circuit. Also, the capacitor (C₁, C₂) connected in switches are a common using by resonance capacitor and ZVS capacitor. and circuit analysis used state equation of each part modes. Also we conform a rightfulness theoretical analysis by comparing a parameters values and simulation values obtained from simulation using Power MOS-FET as switching devices.

The proposed converter connected by two capacitors in parallel with switching devices. The converter reduce the switching loss and switching noise and voltage stress at switching instants. This paper describes the operating principle of the proposed LC and LCC-Type Load Parallel Resonant DC-DC Converter Using ZVS capacitors. The analysis of the proposed circuit are described of using the normalized parameters to be required in all the design steps. Also, the principle of basic operating and the characteristics of driving were estimated switching frequency and the parameter. And, the data fur designing got by the characteristic values example of the design's method was proposed. And, this paper conform a rightfulness of theoretical analysis by comparing a theoretical values obtained from simulation results and experimental values obtained from experiment using MOSFET as switching device.
