ABSTRACT:
The switched-mode power supply according to the invention has a power factor correction circuit, which operates on the principle of a current pump and has a first coil for damping voltage spikes, as well as a second coil for power factor correction. The two inductances are in this case connected in series and are arranged on a coil former and on a common core. In one preferred exemplary embodiment, an E/E ferrite core is used as the core, and a coil former with chambers is used as the coil former, with the windings of the two inductances being arranged in different chambers. An empty chamber, which is located in the region of the air gap in the core, is advantageously arranged between the two inductances. This partially decouples the two inductances by means of the air gap, so that the damping response of the first inductance is better.
