Claim:
1. A device for measuring a chopped current capable of flowing in a circuit having an H-bridge structure including a first branch and a second branch, the device comprising: two transformers respectively connected to a branch of the H-bridge, the transformers respectively comprising a primary circuit configured for the flow of a chopped current, and a secondary circuit; two circuits for demagnetizing the two transformers; and two measuring circuits respectively connected to the terminals of the secondary circuit of an associated transformer, the measuring circuits respectively including at least one unit which comprises a first switch and a second switch connected in reverse, the two switches being respectively implemented by a transistor and being capable of being controlled so as to: the measuring circuits including a common measuring resistor connected via a first terminal to the ground, and via a second terminal to the source of the first transistor of the first measuring circuit and to the source of the first transistor of the second measuring circuit.
