In this paper, the authors control the common mode leakage current by using virtual dc bus with PV systems. The power which they receive form the PV panel is not a constant supply due to various condition. In order to overcome this issue, they are using buck boost converter for generating constant voltage supply to the inverter. The negative pole of the DC bus is connected directly to the neutral line of grid and the stray capacitance between the PV panels and ground is bypassed. Due to this, the common mode ground leakage can be suppressed completely.
