TRANS-Z-SOURCE INVERTER FOR PHOTOVOLTAIC GENERATION SYSTEM

S.Subanitha , M.Ramkumar

The Trans-Z-source inverters has features such as DC input source and reduced capacitor counts. In the proposed system,photovoltaic module implemented instead of DC source in the trans Z source inverter.The battery is connected across the Capacitor which acts as the energy storage device.With the energy storage device,inverter is able to operate even in the case,the available PV power is higher than the load power and also when available PV power is lower than the load power.Here the power not consumed by the load can be used to charge the battery.The main advantage of this system is because of the implementation of the battery bank, voltage regulation takes place and oscillations on the AC grid can be reduced.In addition to this,it has benefits of high voltage gain and reduced voltage stress
