Title:
CURRENT SAMPLING CIRCUIT OF ELECTROMAGNETIC CLUTCH CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2019/192297
Kind Code:
A1
Abstract:
A current sampling circuit of an electromagnetic clutch controller. The current sampling circuit of an electromagnetic clutch controller comprises: a pre-driving module, a switch circuit, a freewheeling circuit, and a current sampling circuit. The pre-driving module is configured to control the turn on and turn off of an MOSFET tube (Q1) in the switch circuit; The switch circuit is configured to adjust the current magnitude of a load coil in an electromagnetic clutch controller. The freewheeling circuit is configured to consume residual energy on the load coil; The current sampling circuit is configured to calculate the current value of a load coil end. The current sampling circuit of the electromagnetic clutch controller can acquire the real current at any moment at the coil end of the electromagnetic clutch controller, so that the electromagnetic clutch controller can use a current closed-loop control method, ensuring that the controller can flexibly and quickly engage/disengage the gear, improving the driving and riding experiences.
