Patent
CA 2077859
A device for protecting a power supply which is preferable for television receivers, etc. is disclosed. A diode is connected between a secondary anode of a power supply voltage feedback control photocoupler and a load of the power supply. When a voltage on the load is lowered due to an abnormality such as short-circuiting of the load, a control current for the power supply voltage feedback control photocoupler flows to the load via that diode to interrupt the control current and stop the operation of the power supply. Overheating and/or breaking of components due to eddy current can be prevented on occurrences of abnormalities such as short-circuiting.
L'invention porte sur un dispositif servant à protéger l'alimentation en énergie d'un téléviseur, etc. Une diode est raccordée entre l'anode secondaire d'un photocoupleur de commande de la réaction de tension d'alimentation électrique et une charge électrique. Lorsque la tension de la charge est abaissée en raison d'une anormalité comme un court-circuitage de la charge, la diode permet de faire passer un courant de commande du photocoupleur de commande de la réaction de tension jusqu'à la charge afin d'interrompre le courant de commande et de mettre fin à l'alimentation en énergie. Il est ainsi possible de prévenir la surchauffe ou le bris de composants en raison de courant tourbillonnaire provoqué par des anormalités comme un court-circuit.
