Zusammenfassung:	A circuit ( 1 ) used for power factor correction, corresponds to a known circuit that includes a high-frequency frequency source ( 15 ) for generating a high-frequency voltage (Uf) for a pump capacitor ( 14 ). The high-frequency voltage source ( 15 ) has two on/off switches ( 151, 152 ) connected in series that generate, at an electric connection point ( 153 ), a square wave voltage (U 1 ) that varies between these two switches with a frequency (f) of at least 1 megahertz. The voltage source further includes a smoothing device ( 150 ) for generating from the square wave voltage a smoothed voltage (Uf) for the pump capacitor, whereby the smoothed voltage varies with a frequency (f) of at least 1 megahertz.
