Abstract (en)
[origin: EP1154140A2] The drive circuit has a first switching device (115,116) switched off to minimize battery voltage dependency during rapid transitions and a re-charging circuit (1) that supplies voltage to the magnetic valve(s) (100-102;200-202) via a third switching device (140,141) during a booster phase from energy stored in a storage capacitor (145). The storage capacitor is charged with a pre-stabilized recharging voltage produced from the battery voltage.
