Abstract (en)
[origin: EP0945609A2] The load (EV1-EV4) has one connection to earth via a switch (T1-T4) and another connection to a supply voltage. The inductance has a first connection which can be connected via a second switch to earth and a second connection connected to the supply voltage. The method involves driving the switches so that when the current flow through the inductance is interrupted, released energy is used to switch the load (EV1-EV4). An Independent claim is also included for an arrangement for switching at least one inductive load.
