Current invention presents a transformer-less grid connected inverter, capable of extracting maximum power from two PV arrays while ensuring minimum leakage current flow.

The Technology The grid connected inverter comprises

• A first photo voltaic (PV) array and a second PV array.
• A first set of switches and first inductor and second set of switches and second inductor.
• Both PV arrays are operated simultaneously to fed positive sinusoidal current and negative sinusoidal current to grid.
• The first PV generates positive sinusoidal current in positive half cycle by operating first set of switches.
• The first PV array generates negative sinusoidal current in negative half cycle by operating second set of switches.
• The second PV array generates positive sinusoidal current in positive half cycle by operating second set of switches.
• The second PV array generates negative sinusoidal current in negative half cycle by operating first set of switches.
