Parallel controller structures are often used for the control of harmonic components in those power converters including harmonic compensation functions. The harmonic compensation can be distorted during saturation of the power converter output. This paper proposes an implementation of the realizable references anti-windup technique suitable for parallel controllers in multiple reference frames. The proposed implementation does not require a particular type of controllers nor special formulations. It allows canceling individual controller outputs during steady-state saturation to improve the waveform quality. Different saturation options are analyzed.
