Abstract
A method and a circuit for controlling a triac intended to be series-connected with a resistive element of positive temperature coefficient or a capacitive element, and a winding for starting an asynchronous motor, for supply by an A.C. voltage, the present invention including the steps of: detecting a voltage representative of the voltage across the series connection of the element and of the triac; comparing this detected voltage with respect to a threshold; and blocking a turning back on of the triac when the threshold has been exceeded.
