Abstract
1. A switched-mode power supply for a device which can be remote-controlled, particularly for a television set, having a starting circuit for the switching transistor (13), which circuit is disposed at the side of the switched-mode power supply transformer (21) connected to the mains, and a protective circuit or the switching transistor (13), likewise disposed at the side connected to the mains, comprising the following features : a) the remote-control receiving section (1) is disposed at the side connected to the mains and is supplied with an operating voltage produced directly from the mains, b) the remotely controllable on and off instructions are fed to an evaluation circuit which is connected to the mains and releases the switching instructions at the side connected to the mains, c) all other remotely controllable instructions are fed via a mains isolator (11) to a processing circuit (mu P), d) during the starting operation when the secondary voltages are rising in the switched-mode power supply transformer (21), the starting circuit is separated by a pulse width modulator (22) disposed at the secondary side and delivering control signals via a mains isolator (19).
