Abstract
A rectifier circuit matched for power factor correction. A first diode (D ), a second diode (D ), a third diode (D ) and a fourth diode (D ) are in a bridge arrangement. A first pole ( ) and a second pole ( ) of the bridge arrangement are connected to a source (U) which has at least one AC voltage component. An inductance (L ) is arranged in series with the third pole ( ) or the fourth pole ( ) of the bridge arrangement. A capacitance (C ) is connected between the first pole ( ) and the second pole ( ), and two of the four diodes (D , D , D , D ) are in the form of fast diodes.
