ABSTRACT:
A very inexpensive and compact circuit arrangement having low electrical losses and which supplies a load with energy from an AC voltage source by means of a switch-mode power supply unit (22). The load includes at least two partial loads (3, 4) and electric energy is supplied to one of the partial loads (3 or 4) through the switch-mode power supply unit (22) and, as desired, also to at least a second one of the partial loads (4 or 3) directly from the AC voltage source.
