Abstract	This paper proposes a non-isolated high efficiency high gain DC-DC converter using zero voltage switching for renewable/green power supply system with photovoltaic (PV) cell or fuel cell. Proposed topology uses interleaved structure of boost converter with winding coupled inductor to offer higher power handling capacity, lower ripple for input current and lower semiconductor voltage stress. The power switches are turned on using zero voltage switching (ZVS) and the switch turned off voltage spike is suppressed by using boost type active clamping technique. This enables the use of lower voltage and $R_{DS-ON}$ MOSFET switch with low switching and conduction losses. Diode turn off current falling rate is controlled by the leakage inductance of coupled inductor and by choosing proper value of leakage inductance, diodes can be turned off using zero current switching (ZCS) and diode reverse recovery problem is alleviated. The significant feature of the proposed topology includes continuous input/output current operation with rid of extreme duty cycle and limited reactive components size. The proposed converter operating modes are analyzed and theoretical waveforms are validated through simulation results.
