Modeling and Simulation of Single-Phase Full Bridge Two-Level PV H6 Inverter Connected to Grid

Abstract:

PLECS is used to model the PV H6 inverter connected to grid and good results are obtained. First, several common topologies of PV inverters are introduced. Then the unipolar PWM control strategy is described for PV H6 inverter. Third, PLECS is briefly introduced. Fourth, the modeling of PV H6 inverter is presented with PLECS. Finally, a series of simulations are carried out. The simulation results tell us PLECS is very powerful tool to real power circuits and it is very easy to simulate LCL filter. They have also verified that the unipolar PWM control strategy is feasible to control the PV H6 inverter.
