This paper describes the non-isolated high step-up DC-DC converter using Zero Voltage Switching (ZVS) Bi-directional Integration Technique (BIT). The DC-DC converter which integrates PV and battery power for high step up applications are proposed. Coupled inductors are used to attain the high step up voltage gain and also used to reduce the voltage stress of input side switches. The operation need not to be changed when the transition between charging and discharging occurs. It is also capable of operating simultaneously in tracking the maximum power from the sun and generates the output. This implies the usage of PV panel most of the time.
