Power control for grid connected applications based on the phase shifting of the inverter output voltage with respect to the grid voltage
A new control strategy for grid connected system has been described and developed. The control strategy is based on phase shifting of Vinv with respect to the Vgrid. The strategy requires few ma to achieve a high PF> 0.99 over wide range of Iout. A digital implementation on FPGA platform. Validation of simulation results by experimental tests.
