Design and Implementation of New Topology for Solar PV Based Transformerless Forward Microinverter
Premkumar M,Sumithira T.R 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.1
Recently, transformerless inverters play a vital role for single phase low voltage solar photovoltaic (PV) due to low cost, lesser weight, small size and high efficiency. However, the leakage current produces electromagnetic interferences (EMI), current distortion on the grid with additional losses which affects the performance of the inverter. In this paper, a new inverter topology, to deal with the problem of leakage current is proposed. The various conventional H6 topologies are simulated, compared and evaluated based on the leakage current, performance and safety with the proposed inverter topology. This work focuses on transformerless inverter which is best suitable for Module Integrated Converter (MIC) or microinverter. The proposed topology is employed with unipolar sinusoidal pulse width modulation, and it can reduce the common mode (CM) current. The performance analysis is carried out on different topologies using MATLAB/Simulink environment and the proposed inverter experimentally verified on a 150W prototype. Based on the analysis, simulation and experimental results, the comparison also presented for future reference.
