Resonant Converter Circuit

摘要

A resonant converter circuit comprising a controller having a Vbusdiv-input-terminal configured to receive a Vbusdiv-input-signal; and a Vbus-compensation-network. The Vbus-compensation-network comprising: a Vbus-input-terminal configured to receive a bus-voltage-signal; and a Vbusdiv-output-terminal configured to provide the Vbusdiv-input-signal to the controller; a reference terminal; an AC-impedance-network; connected between the Vbus-input-terminal and the Vbusdiv-output-terminal, wherein the AC-impedance-network is configured to apply an AC transfer function to the received bus voltage signal; a DC-impedance-network connected between the Vbus-input-terminal and the Vbusdiv-output-terminal, 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 is configured to control operation of a resonant converter in accordance with the Vbusdiv-input-signal.
