ABSTRACT:
A power-supply circuit receives its power from an a.c. source (1) which, in specific time intervals is connected to a power-storage device (6) to feed power thereto. The power supply circuit includes a switch (10) which is periodically actuated by a control circuit (13) to take power from the power-storage device. Interference is suppressed in a simple, space-saving and cheap manner in that the control circuit (13) turns on the switch (10) only at times outside the time intervals (t2-t1) in which the a.c. source is connected to the power-storage device.
