Abstract:
An AC/DC converter comprising:a first rectifier arrangement for generating a rectified AC voltage from an AC voltage at an input of the AC/DC converter;a first smoothing capacitor arrangement for smoothing the rectified AC voltage;a resonant converter comprising resonant circuit elements for converting a voltage at an output the first smoothing capacitor arrangement into a DC output voltage at an output of the AC/DC converter;an inductive element arranged between the first rectifier arrangement and the first smoothing capacitor arrangement, said inductive element being magnetically coupled to an inductive resonant circuit element, andmeans for capacitive coupling a point between the first rectifier arrangement and the first smoothing capacitor arrangement to a point within the resonant converter, such that a potential modulated at an operating frequency of the resonant converter is fed back during operation of the AC/DC converter.
