ABSTRACT:
Television receiver including a switched-mode power supply which is regulated and capable of functioning both in self-oscillating mode and under the control of a line frequency synchronization. During normal operation there is synchronization, and the line time base supplies most of the supply voltages to the circuits of the receiver. To change to the stand-by state the drive of the line transistor is stopped, which stops most of the circuits depending thereon. The switched-mode power supply continues to function but then in the self-oscillating mode, and supplies the stand-by device via a secondary winding of its storage inductor.
