Title:
PROTECTIVE CIRCUIT CAPABLE OF PREVENTING ERROR VOLTAGE ACCESS
Document Type and Number:
WIPO Patent Application WO/2023/092883
Kind Code:
A1
Abstract:
A protective circuit capable of preventing error voltage access, comprising a first unidirectional conduction element, a triode control circuit, a first triode, a first capacitor, a Darlington transistor, a first resistor, a second resistor, and a relay. A contact of the relay is connected in series between an input end and an output end. The first unidirectional conduction element has a first end connected to the input end and a second end that is connected to a first end of each of the first resistor, the first triode, the first capacitor, and the Darlington transistor, respectively. The triode control circuit is connected to a second end of the first resistor and a controlled end of the first triode, respectively, and a second end of the Darlington transistor is connected to a controlled end of the relay. According to the present invention, the input end can be disconnected from the output end when an error voltage is input.
