Abstract (en)
[origin: EP1400684A2] The circuit includes a control unit for generating pulse-width modulated signals for driving an electromagnetic regenerative valve. A solenoid coil is supplied with the signals via a switch. A free-running diode is provided on the solenoid coil for suppressing high induced voltages.
