MULTIPLEXED OUTPUT SHORT-CIRCUIT PROTECTION CIRCUIT

WIPO Patent Application WO/2021/128716

A1

A multiplexed output short-circuit protection circuit. The multiplexed output short-circuit protection circuit comprises a power supply module (1), an input winding (2) and a plurality of output windings (3), wherein the power supply module (1) is used for supplying power to the input winding (2), and the output windings (3) are used for coupling a power source signal transmitted by the input winding (2) and outputting isolation power source signals to corresponding loads; a plurality of short-circuit detection circuits (4) used for adjusting an output short-circuit control signal according to the isolation power source signals output by the corresponding output windings (3); and a short-circuit protection circuit (5) used for adjusting, according to short-circuit control signals output by all the short-circuit detection circuits (4), a power supply control signal outputted to the power supply module (1), so as to control a power supply state of the power supply module (1) to the input winding (2). The cost for realizing multiplexed outputting of isolation power sources is effectively reduced, the short-circuit protection for each isolation power source output branch is realized, and the probability of devices in a multiplexed output line of isolation power source signals being burnt out is reduced.
