A power supply unit for an electrical control device having a transformer with a primary coil that can be actuated by means of a switchable primary switch and at least one secondary coil. The primary coil and the at least one secondary coil are arranged on a common magnetic core. The secondary coil provides at least two outputs with controllable output voltages, and the secondary coil is assigned a switchable secondary switch for each of the at least two outputs. The power supply unit comprises a signal processing and calculation unit that is set up to actuate the primary switch and the secondary switches by means of pulse generators. The outputs may be switched sequentially to provide at least two controllable output voltages.
