    Abstract: A circuit includes a first half bridge including a first controllable semiconductor switch and a first diode. The first controllable semiconductor switch is coupled between a first constant supply potential and a center tap of the first half bridge. The first diode is coupled between the center tap and a constant reference potential. A second half bridge includes a second diode and a second controllable semiconductor switch. The second diode is coupled between a second constant potential higher than the first potential and a center tap of the second half bridge. The second controllable semiconductor switch is coupled between the center tap and the constant reference potential. Driver circuitry controls the conducting state of the first and the second semiconductor switch thus controlling the current flow through a field connectable between the center taps.
