Abstract:
A circuit for power-factor correction havinga bridge rectifier (18) with a first and a second input connection (14, 16) in which case an AC voltage source (10) can be arranged between the first and the second input connection (14, 16), and having a first and a second output connection (30, 32),an actuation and load circuit (24),at least one energy storage apparatus, (20; 20a; 20b), whose first connection is connected to a connection (28) in the actuation and load circuit (24), in which case the signal which can be tapped off at this connection (28) in operation is at a considerably higher frequency than the output signal from the AC voltage source (10), andan energy storage capacitor (C.sub.s),whereinthe energy storage capacitor (C.sub.s) is arranged in parallel with the output connections (30, 32) of the bridge rectifier (18), andthe second connection of the at least one energy storage apparatus (20; 20a; 20b) is connected to one of the two input connections (14; 16) of the bridge rectifier (18).
