A circuit for driving an inductive load may include an input, an output, a first switch, and at least one capacitor. The first switch may cause the capacitor to be charged by the supply voltage via the inductive load. A device may discontinue the charging of the capacitor when the voltage has reached a predetermined level greater than that of the supply voltage. A first and a second diode may prevent the capacitor from discharging via the first switch and blocking inductive load current from entering the power supply, respectively. A second switch and the capacitor may be connected to the third switch to cause discharging of the capacitor via the third switch into the inductive load. Closing of the first switch may cause a current sufficient for actuating a mechanical valve to be induced in the inductive load.
