In order to broaden the adaptation range of the conventional fixed active damping grid-side current harmonic suppression method, an adaptive active damping-based grid-side current harmonic suppression method is proposed in this paper. Besides, the totem-pole bridgeless PFC converter input impedance characteristics and Hermite interpolation-based active damping method are theoretically analyzed. Finally, the proposed method is validated on a 1.5 kW GaN totem-pole bridgeless PFC converter.
