A Zero Voltage Switching (ZVS) Cuk converter is presented in this paper to reduce the switching losses of main switch. An auxiliary switch and a clamp capacitor are connected in parallel with the main switch to absorb all the energy stored in the leakage inductance of the transformer. The ZVS operation of main switch is achieved by the resonance with the resonant inductor and output capacitor of main switch. The ZVS operation of auxiliary switch is achieved by the resonance with the resonant inductor and the clamp capacitor. Therefore, both switches are turned on at ZVS. The principle of operation,system analysis and design consideration are presented. Finally, simulations based on an 270W(18V/15A) are provided for the proposed converter.
