PCT No. PCT/FR96/00040 Sec. 371 Date Sep. 23, 1997 Sec. 102(e) Date Sep. 23, 1997 PCT Filed Jan. 10, 1996 PCT Pub. No. WO96/21864 PCT Pub. Date Jul. 18, 1996A bidirectional current sensor including a transformer having a primary winding arranged in a circuit likely to be run through by a current to be measured, a secondary winding, an impedance for demagnetizing the transformer, and a measuring resistor connected to the secondary winding via a switch controlled to be on when a current is likely to run through the primary winding. It applies in particular to the detection of currents in bidirectional voltage converters.
