  • Controller for power inverter
    Patent number: 11309786
    Abstract: Herein provided is a controller for a current inverter. The controller comprises a reference generator configured for obtaining source voltage and current values from an electrical source, generating a voltage error function based on source and reference voltages, and generating a current error function based on source and reference currents. The controller also comprises an output controller for receiving from the reference generator the voltage and current error functions and configured for producing at least one control signal based on the voltage and current error functions. The controller also comprises a state feedback controller configured for: adjusting the at least one control signal, based on parameters of the electrical source, to produce at least one adjusted control signal, and outputting the at least one adjusted control signal to the current inverter.
    Type: Grant
