Abstract: The module for exchanging information by carrier-currents (22, 24) for controlling an electrical member (12, 14) includes first receiver means (34A, 36A) for receiving an information-conveying signal. The first receiver means (34A, 36A) may take on two states, respectively an activated state and a deactivated state. The module (22, 24) further includes second receiver means (34B, 36B) for receiving a wakeup signal for activating the first receiver means (34A, 36A) to switch from the deactivated state to the activated state.

Abstract: This device for measuring a chopped current (ie) includes a pulse transformer (10). The transformer includes a primary circuit (12) in which the chopped current flows and a secondary circuit (14) in which there flows an output current (is) that is proportional to the chopped current, the secondary circuit of the transformer having two output terminals (16, 18) between which there is connected an output current measuring circuit (22). The measuring circuit further includes transformer demagnetizing means (20). The measuring circuit includes a switch (32) and means (33) for synchronizing said switch with the chopped current (ie) to enable the output current (is) to flow through the measuring circuit (22) whenever the chopped current is strictly positive and whenever it is strictly negative, and to prevent any flow of current through the measuring circuit when the chopped current is zero.
