A novel control method for grid side inverters under generalized unbalanced operating conditions

In this paper, a generalized method for grid side inverter control under unbalanced operating conditions is proposed. The control method presented in this paper provides complete harmonic elimination in line currents and DC link voltage with adjustable power factor. The method is general and can be used for all levels of imbalance in grid voltages and line impedances. The control algorithm proposed in this paper has been implemented by using Matlab Simulink and dSpace RT1104 control system. Simulation and experimental results presented in this paper are in excellent agreement.
