Modeling and Simulation of a Novel HERIC PV Inverter
PLECS is used to model the PV inverter connected to grid and good performances are obtained.First, several common topologies of PV inverters are introduced.Then the unipolar PWM control strategy is described for HERIC PV inverter.Third, PLECS is briefly introduced.Fourth, the modeling of HERIC PV inverter is presented with PLECS.Finally, a series of simulations are carried out.The simulation results tell us PLECS is a 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 HERIC PV inverter.
