Performance Analysis of Common Issues In the PV Transformer-Less Inverter Topology

Abstract

The Photovoltaic (PV) Panel is part and parcel in recent time where it has been used in the electricity generation through either in Transformer based or Transformer-less inverter topology. To reduce the limitation of using transformer based system, no transformer topology is highly popular where the main and common issue is leakage current through parasitic capacitance. In this paper, main focusing issue is leakage current hence, a new topology is introduced and for leakage current reduction purposes, Pulse Width Modulation (PWM) has used as a switching combination and compared with another topology.
