A zero-current-switching (ZCS) two-switch DC-DC forward converter with variable-inductor is presented in this paper. The quasi-resonant technique is employed to achieve ZCS operation. This variable inductor technique is used to reduce the switching losses and the peak value of the outputdiode current. Thus, the conversion efficiency can be improved. Moreover, the voltage across the active switch is clamped at the DC-source input voltage. So, the voltage stress of the active switch is less than that of the conventional DC-DC forward converter. Finally, a prototype circuit is implemented to verify the performance.
