Abstract
A power supply system with self-excited drive function includes a power supply apparatus, a logic disconnection circuit, a self-boosting circuit, a protection circuit, and a current sensing unit. The logic disconnection circuit is coupled between a positive power wire and a negative power wire. The self-boosting circuit converts a voltage into an auxiliary voltage, and the self-boosting circuit is coupled to the logic disconnection circuit to receive the auxiliary voltage. The current sensing unit outputs a current sensing signal according to a current flowing through the positive power wire or the negative power wire. The protection circuit makes a short circuit or an open circuit between the positive power wire and the negative power wire according to the current sensing signal. The logic disconnection circuit disables or enables the self-boosting circuit according to the voltage between the positive power wire and the negative power wire.
