Circuit arrangement for operating light sources with power factor correction

摘要

The circuit arrangement has a rectifier (D7-D10), diodes (D1-D6), storage capacitors (C1,C2), an inverter (T1,T2), a reactance network, a coupling between the reactance network and a node and a pump capacitor (C3) connected to the node and the positive rectifier output. The circuit arrangement has a second pump capacitor (C4) that is connected to the node and to the negative rectifier output.
