Abstract
Photovoltaic (PV) power-generation systems are suitable increasing significantly and predominant indistribution generation systems. A high voltage gain converter is necessary for the module’s grid connection through a dc–ac inverter or for battery charging for standalone PV system.This paper proposes a new high step up DC-DC converter with floating active switch which acts as a high state drive. This floating active switch segregates energy from the PV panel when the AC module is off. It also regulates the DC interface between the DC-AC converters. The high step up voltage conversion ratio is accomplished with several turns ratio of a coupled inductor and appropriate duty ratios. The energy stored in the leakage inductor with the help of magnetizing inductor of a coupled inductor is efficiently recycled to the load through the output capacitor. With an input voltage of (Vin) 15V and 250V output voltage is obtained. An output power of 97W is also obtained from the designed converter circuit. Its maximum full load efficiency is better than conventional convert model.
