<p>The control device (1) has a drive circuit (7), in turn having a number of modular circuits (10) - one for each inductor (2) - activated selectively and receiving timing signals (T), and a common circuit (11) connected to the modular circuits (10) and cooperating with the activated modular circuit (10) to supply the respective inductor (2). Each modular circuit has a first controlled switch (21, 22) connected between a first input terminal (16) and a respective first output terminal (19), and a second controlled switch (23, 24) connected between the respective first output terminal (19) and a storage capacitor (25); and the common circuit (11) has a third controlled switch (26, 27, 28) connected between the storage capacitor (25) and a respective second output terminal (20), and cooperating with the second controlled switch (23, 24) to selectively transfer energy between the storage capacitor (25) and the respective inductor (2). <IMAGE></p> |
