Abstract
A switched mode power supply is provided. The switched mode power supply includes a transformer, which includes at least one primary winding connected to a DC voltage via a switching element and a secondary winding connected to a load via a rectifier circuit including at least one diode, and at least one piezoelectric fan which generates an air flow at the transformer and/or at the switching element and/or at the diode. The air flow produced can be guided in a targeted manner onto the components to be cooled, with the air flow remaining low and therefore, no contamination by air particles arises.
