Title:
MOTOR CONTROLLER ELECTRICAL-DISCHARGE CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/192295
Kind Code:
A1
Abstract:
Disclosed is a motor controller electrical-discharge control circuit, comprising a discharge signal transmission circuit, a switching circuit, and a discharge circuit; the switching circuit is separately connected to the discharge signal transmission circuit and the discharge circuit; the discharge circuit is also connected to a bus bar positive electrode; the input terminal of the discharge signal transmission circuit is connected to the discharge signal output pin of the motor controller; the output terminal of the discharge signal transmission circuit is connected to the bus bar negative electrode; the discharge signal transmission circuit outputs a control signal to the switching circuit according to the received discharge signal; the switching circuit is connected to the bus bar positive electrode, the bus bar negative electrode, and the output terminal of the discharge signal transmission circuit, and, according to the control signal received, causes the switching circuit to turn on, then discharge by way of the discharge circuit. The motor controller electrical-discharge control circuit of the present embodiment is capable of performing active rapid discharge, preventing the hazard of high-voltage leakage and ensuring the safety of the motor controller.
