Abstract:
A method for detecting the state of at least one element of a circuit comprising one or several loads, powered by an A.C. voltage and in series with at least one first switch. The state of the element is obtained by analyzing, at several times in a period of the A.C. voltage, the amplitude of a current sampled from the junction point of the load and of the first switch.
