Beschreibung
Zusammenfassung:	An electrical device includes at least a first coil (L1) and a second coil (L2), an input terminal and an output terminal, an electrical circuit including a plurality of switches (SW1, SW2, SW3), a sensor (12) configured to measure a value of an electrical current circulating between the input and output terminals, and a control unit (14) coupled to the sensor and to the switches.The control unit is configured to automatically open or close one or more of the switches, depending on the measured current value, for connecting one or more coils between the input terminal and the output terminal or disconnecting one or more coils from the input terminal or the output terminal.
