Title:
ELECTROMAGNETIC CLUTCH CIRCUIT AND AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2022/032763
Kind Code:
A1
Abstract:
An electromagnetic clutch circuit and an automobile. The electromagnetic clutch comprises: an anti-reverse-connection unit and a clutch half-bridge working unit, wherein the clutch half-bridge working unit comprises a negative electrode access end and a positive electrode access end; and the positive electrode access end of the clutch half-bridge working unit is connected to an external power source by means of the anti-reverse-connection unit. The anti-reverse-connection unit comprises a MOS transistor and a control signal access end, wherein the MOS transistor realizes turning-on/turning-off control between the positive electrode access end of the clutch half-bridge working unit and the external power source according to a pulse control signal received by the control signal access end, thereby realizing anti-reverse-connection and anti-reverse-direction voltage overshoot functions of the electromagnetic clutch circuit. The electromagnetic clutch circuit realizes anti-reverse-connection and anti-reverse-direction voltage overshoot functions of a circuit by using very few devices, such that a power source voltage reverse-connection fault and a reverse-direction voltage overshoot fault are effectively prevented.
