Abstract

A method is provided for limiting double-frequency internal power distortion in a power system. The method includes receiving an input voltage from a voltage source at a power converter from which an output power is provided to an electrical load, measuring the output power having a waveform with a steady-state component and a double-frequency transient component, executing computer-readable program code, via processing circuitry, to determine a compensating waveform equal in amplitude to the double-frequency transient component, and that is anti-phase to the double-frequency transient component, and causing the power converter to generate the compensating waveform such that the waveform and the compensating waveform superpose, and the double-frequency transient component of the waveform and the compensating waveform destructively interfere, leaving the steady-state component that is delivered to the electrical load.
