Abstract: AC to DC signal conversion for use in applications including conditioning of signals supplied by inductive position sensors that are employed in aircraft electrical and electronic systems. First and second switching circuits (14 and 16) are synchronously switched between operational states in which an applied AC signal is supplied to the switching circuits and a second operational state in which the switching circuits supply charge (current). When one switching circuit (e.g., 14) is in the first operational state, the second switching circuit (e.g., 16) is in the second operational state so that one switching circuit senses the AC signal during positive half cycles and the other switching circuit senses the AC signal during negative half cycles. A pair of capacitors (18 and 20) are connected between a pair of output terminals.
