Abstract


In this paper, a high step-up topology employing a ZVS soft-switching technique in forward-flyback DC-DC converter to improve the voltage-gain is presented. The ZVS soft-switching technique implemented in a DC-DC converter suppresses the voltage spikes, which reduces the switching voltage stress and improves the voltage gain of the converter. A 60 W SFFB DC/DC converter test system is implemented in MATLAB/SIMULINK to verify the results. The comparison is also made between the hard-switching and soft-switching technique in a forward-flyback converter. From the result it is evident that the implementation of the soft - switching technique in a forward-flyback converter improves the voltage gain. Hardware prototype of the proposed converter also has been implemented to confirm the results.
