Abstract

A resonant converter circuit comprising a controller (510) having a Vbusdiv-input-terminal (556) configured to receive a Vbusdiv-input-signal; and a Vbus-compensation-network (501). The Vbus-compensation-network (501) comprising: a Vbus-input-terminal (552) configured to receive a bus-voltage-signal; and a Vbusdiv-output-terminal (550) configured to provide the Vbusdiv-input-signal to the controller (510); a reference terminal (554); an AC-impedance-network (560, 540, 542, 558) connected between the Vbus-input-terminal (552) and the Vbusdiv-output-terminal (550), wherein the AC-impedance-network is configured to apply an AC transfer function to the received bus voltage signal; a DC-impedance-network (540, 542) connected between the Vbus-input-terminal (552) and the Vbusdiv-output-terminal (550), wherein the DC-impedance-network is configured to apply a DC transfer function to the received bus voltage signal. The DC transfer function is different to the AC transfer function. The controller (510) is configured to control operation of a resonant converter in accordance with the Vbusdiv-input-signal.
