Power supply unit for converting a mains AC voltage into at least one DC voltage, without using a transformer

摘要

The subject matter of the invention is a power supply unit for converting a mains AC voltage into at least one DC voltage without using a transformer and using at least one rectifier circuit. At least one energy storage device, which is supplied from the mains AC voltage and contains a winding (5, 12) of an inductor (6) in series with a capacitor (7) is connected, via a rectifier (10, 14), to an output (9) of the rectifier circuit (1). <IMAGE>
