Abstract
The present disclosure provides a silicon-controlled silicon (SCR) current-protection circuit. The SCR circuit includes an SCR detection circuit and a protection circuit, a first terminal of the SCR detection circuit being connected to a current sampling point on an output terminal of an SCR device, a second terminal of the SCR detection circuit being connected to a power conversion circuit, a third terminal of the SCR detection circuit being connected to a first terminal of the protection circuit, and a second terminal of the protection being connected to the power conversion circuit. When the SCR device is connected to the SCR current-protection circuit, the SCR detection circuit is configured to detect a current flowing through the current sampling point, convert the current to a voltage, and output the voltage to the protection circuit. The protection circuit is further configured to control on and off states of the power conversion circuit based on the voltage.
