Beschreibung
Zusammenfassung:	An AC-DC power converter includes: an AC rectification circuit configured to convert an AC line voltage into a rectified line voltage; a charge-pump-based power factor correction sub-converter configured to provide a DC-bus supply voltage; a resonant sub-converter configured to convert the DC-bus supply voltage to a DC output voltage or DC output current, the resonant sub-converter including: a resonant tank configured to convert the DC-bus supply voltage to a resonant voltage or current; and an output rectification circuit configured to generate the DC output voltage or DC output current from the resonant voltage or current to supply a converter load, and a controllable switch network shared by the charge-pump-based power factor correction sub-converter and the resonant sub-converter.
