N2 - It is well-known that employing PI+Notch controller as DC link voltage regulator in power factor correction rectifiers (PFCR) permits attaining better transient response to step-like load variations compared to widely-used type-II controller under similar grid-side current total harmonic distortion (THD) and phase margin constraints. However, in case grid frequency uncertainty is considered, PI+Notch controller design process yields a system of four nonlinear analytical equations with five unknowns, giving rise to infinite amount of feasible coefficient sets. This work proposes a methodology for identifying the set optimizing PFCR transient response to a step-like load variation. Simulations accurately validate the proposed design methodology.
