Abstract (en)

[origin: EP0945610A2] The first connection of the inductance (L1) can be connected to earth via a first switch (T1) and a second connection is connected to the supply voltage (UBAT). A second inductance (L2) can be connected to earth via a second switch (T2). The energy released when the current flow to the second inductance is interrupted is used to switch the first inductance. An Independent claim is also included for an arrangement for switching an inductance.
