Abstract
Disclosed is a method for at least partially removing the oscillations occurring at the end of a current discharge through the structural diodes for a switching structure supplying power to an inductive load in the form of an H-bridge and including two controlled high or low power switches forming part of a high circuit or a low circuit, respectively, between a respective output and a power source or a ground, the switching structure having one of its outputs below the ground potential and the other above the potential of the power source during the current discharge through the structural diodes. A detection or anticipation of the end of discharge and a forced preservation of a freewheel after the detection of the end of discharge are carried out, the forced preservation of the freewheel after the detection of the end of discharge taking place for a predetermined preservation time.
