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.

A safety shutdown apparatus with self-driven control is coupled to a power-supplying path between a power supply apparatus and a load. The safety shutdown apparatus includes a detection unit, a controllable switch, and a drive circuit. The detection unit is coupled to the power-supplying path, and the controllable switch is coupled between a positive node and a negative node of the power-supplying path. The drive circuit is coupled to the detection unit, the power-supplying path, and the controllable switch. The drive circuit receives an output voltage of the power supply apparatus to turn on the controllable switch, and turn off the controllable switch according to whether the detection unit detects a current flowing through the power-supplying path.
