<p>The circuit makes it possible to limit the overvoltage across the terminals of an inductive load (10) supplied by a source (12) such as an accumulator, through a first switch (14) provided with means of periodic closure for short periods. The limiter comprises a second switch (30), an inductor (20) placed in series with the second switch (30) within a circuit parallel with the load (10), a chopping capacitor (18) in parallel with the first switch (14) and means (34) of controlling the second switch (30) in response to the voltage across the terminals of the load (10). <IMAGE></p> |
