Grid-connected transformerless inverters (GCTIs) are power electronic devices that convert direct current (DC) supply from a renewable energy source such as solar PV energy or wind turbines, to alternating current (AC) electricity that can be used to power up houses, businesses, and grid. As the name suggests, GCTIs do not require a transformer to step up the voltage of the AC output, unlike traditional grid-tied inverters which use a transformer for isolation and voltage regulation. A three-phase Transformerless Inverter Connected to Grid (TICG) is widely practiced in industrial standards. A simple voltage source inverter fed from a Photo Voltaic (PV) source feeding power to the grid without an isolation transformer will cause leakage current and variation in common mode voltage. Though a transformer can provide galvanic isolation, it consumes larger space and decreases the efficiency. The paper presents a three-phase transformerless inverter connected to grid that is fed from a PV source with split capacitor the control at the input side controlled with interleaved pulse width modulation technique can reduce the leakage currents. It also evaluate the performance of power on PV side along with common mode leakage current.
