摘要： A control circuit that drives an electronic actuator. The control circuit includes a direct voltage source, a chopper circuit arranged between the source and an electric actuator, and an electronic control circuit designed to apply to the chopper circuit a command signal of the PWM type, with a predefined ON/OFF switching period and a predetermined duty cycle, for a predefined activation time, to produce a flow, within the electric actuator, of a correspondingly switched current having a nominal duration corresponding to the activation time. The control circuit detects the last whole or complete switching period included within the activation time, splits, in accordance with a predefined duty cycle, the final interval including the last complete switching period and any subsequent fraction of a switching period included within the activation time, and drives the chopper circuit in this final interval.
