TH849C3 - Regulator short circuit protection On the output side - Google Patents

Abstract

The regulator's output short-circuit protection circuit. Contains a relay and a transceiver. And the series Use a transceiver instead of the switch to detect the output side of the regulator while the relay cuts off the input side of the regulator if there is a short circuit. To happen Thus preventing the transceiver The regulator's output is damaged.

Contains trans The cister acts as a switch and a relay coils of the relay, connected to the supply of the regulator and then passed to the collector pin of the transceiver by the transceiver's emitter pin. Sprocket This continues to the output of the regulator with the base leg of the transceiver connected through. Resistor and then go to the regulator supply Where the contactors of such relays oppose their input Of the regulator to ground When the relay operates 2 according to claim 1, if the regulator's supply is positive, the transceiver sounds It will be NPN type or if the regulator's source is negative. Said to be a PNP type
