Energy conversion systems with power control

A system comprising:

• a converter to transfer power between a power source and a load having a fluctuating power demand, the converter comprising a direct current-to-alternating current (DC-AC) output bridge configured to deliver output power to a utility grid;
• a controller to control the DC-AC output bridge of the converter to generate an AC power output, the controller comprising:
• (i) a synchronization function having an input to receive a voltage sensor signal indicative of a grid voltage of the utility grid, the synchronization function configured to generate a phase signal indicative of a phase angle of the voltage sensor signal;
• (ii) a distortion mitigation function to receive the phase signal from the synchronization function and a current sensor signal indicative of a grid current of the utility grid, the distortion mitigation function configured to generate a magnitude signal as a function of the phase signal and the current sensor signal, and
• (ii) a modulator to receive the phase signal from the synchronization function and the magnitude signal from the distortion mitigation function, the modulator configured to generate a modulation signal to control the DC-AC output bridge as a function of the phase signal and the magnitude signal.
