Controller for power inverter

A controller for a current inverter, the current inverter coupled to an electrical source and producing output current for a receiving network, the controller comprising:

• a reference generator configured for:
• obtaining a source voltage value and a source current value from the electrical source;
• generating a voltage error function based on the source voltage value and a reference voltage;
• and
• generating a current error function based on the source current value and a reference current;
• an output controller coupled to the reference generator for receiving therefrom the voltage error function and the current error function and configured for producing at least one control signal based on the voltage error function and the current error function;
• and
• a state feedback controller coupled to the output controller and to the electrical source, the state feedback controller configured for:
• adjusting the at least one control signal, based on a DC ripple level of the electrical source, a double-frequency ripple level of the electrical source, and a DC voltage 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.
