Title:
SILICON CONTROLLED RECTIFIER DRIVE CIRCUIT, SILICON CONTROLLED RECTIFIER DRIVE APPLICATION CIRCUIT, AND ELECTRIC/ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/061149
Kind Code:
A1
Abstract:
The present application discloses a silicon controlled rectifier drive circuit, a silicon controlled rectifier drive application circuit, and an electric/electrical device. The silicon controlled rectifier drive circuit comprises: a control signal receiving end for accessing a control signal. When the control signal receiving end receives invalid level, a switch trigger circuit (10) is turned off to disconnect a gate loop of a silicon controlled rectifier, such that the silicon controlled rectifier is in a turn-off state; when the control signal receiving end receives valid level, the switch trigger circuit (10) is turned on and provides a trigger current for a gate of the silicon controlled rectifier, such that the silicon controlled rectifier is triggered to be turned on when a forward voltage is accessed between an anode and a cathode of the silicon controlled rectifier; and when a reverse voltage is accessed between the anode and the cathode of the silicon controlled rectifier, a one-way conduction element (20) is turned off to disconnect the loop where the switch trigger circuit (10) is located, such that the switch trigger circuit (10) is turned off.
