<p>A power supply device for supplying at least one load (5, 6) with electrical energy from a source (1) contains a switching state (7) for the optional connection of the load or loads (5, 6) on the basis of a switching signal supplied to it, and a control circuit (14) which, in its switched-off state, interrupts the energy supply to the switching stage (7) and to the load or loads (5, 6) and, in its switched-on state, controls the energy supply at least to the switching state (7). Such power supply devices are used in particular in television sets with remote control, for "normal operation" and "standby operation". In order to obtain the advantages of "standby operation" with this device and, on the other hand, to reduce the electrical power consumed and the number of components which are stressed by heating or the application of voltage, the switching signal (on 21) is also supplied to the control circuit (14) for switching over between the switched-off and the switched-on state. …<IMAGE>… </p> |
