Circuit arrangement for the realization of a stand-by working mode in a flyback switching power supply
Abstract
Abstract Translated from German In einem Sperrwandler-Schaltnetzteil besitzt der Transformator (Tr) eine fest mit der Primärwicklung (Wp) und lose mit einer der Stromversorgung der Normallast (RL) eines elektrischen Gerätes dienenden Sekundwärwicklung (WI) gekoppelte Wicklung (W3) zur Erzeugung eines Steuersignals für die Standby-Lastversorgung. In a flyback switched-mode power supply, the transformer (Tr) has a winding (W3) which is fixedly connected to the primary winding (Wp) and loosely coupled to a secondary winding (WI) which serves to supply the normal load (RL) of an electrical device, in order to generate a control signal for the standby -Load supply.
