Controlling an H-bridge of switches, characterized in that during a cycle, the current takes a peak value of constant sign during a continuous portion corresponding to a cycle fraction equal to |<V>/U|, where <V> is the mean voltage applied to the load and U is the voltage of the DC voltage source, said portion being preceded by a cycle portion corresponding to a cycle fraction equal to +E,fra 1/2+EE (1-|<V>/U|) during which the two switches (I1, I2) of the H-bridge which are connected to ground are closed (or open as the case may be), and followed by a cycle portion likewise corresponding to a cycle fraction equal to +E,fra 1/2+EE (1-|<V>/U|) during which the two switches (I1, I2) of the H-bridge which are connected to ground are open (or closed as the case may be).
