Simulation Model of H6 Transformer less Single-Phase Full Bridge PV Grid tied Inverters
Objective
To implement the safety measures of leakage currents in transformer less inverters in photovoltaic generation.
Abstract
Photovoltaic (PV) generation systems are widely employed in transformer less inverters, in order to achieve the benefits of high efficiency and low cost. Safety requirements of leakage currents are met by proposing the various transformers less inverter topologies. The intrinsic relationship between H5, HERIC and H6 is revealed. The proposed H6 topology has been discussed as well. For a detailed analysis with operation modes and modulation strategy one of the proposed H6 inverter topologies is taken as an example. The leakage current in transformer less inverter is stated in detail. In this paper the H6 topology is proposed by using Space vector pulse width modulation (SVPWM). The results are compared with traditional sinusoidal pulse width modulation (SPWM). The proposed topology is simulated using MATLAB Simulink software.
