A novel three-phase grid-tied photovoltaic (PV) non-isolated inverter with improved performance owing to common mode current suppression as well as constant common mode voltage is presented in this paper. To compensate unexpected oscillations in stray capacitor voltage, three additional diodes are used with the full bridge circuit of traditional B6 inverter. Therefore, using total six insulated gate bipolar transistors (IGBTs) and three diodes, the proposed inverter eliminates the pitfalls of conventional grid-tied non-isolated PV inverters. Unipolar sinusoidal pulse width modulation (SPWM) me...
