Abstract
A device and a method are described for triggering an electromagnetic consumer, in particular a solenoid valve for controlling the fuel quantity to be injected. An energy-storing element is arranged between a half-bridge and a voltage source.
Claims12
A device for triggering an electromagnetic consumer, comprising:
- a half-bridge circuit including a first switching element and a second switching element, wherein the electromagnetic consumer is coupled to ground by the first switching element and to a voltage source by the second switching element;
- and
- an energy-storing element coupled between the second switching element of the half-bridge circuit and the voltage source.
A method for triggering an electromagnetic consumer comprising the steps of:
- arranging an energy-storing element between a voltage source and a half-bridge circuit, the half-bridge circuit including first and second switching elements coupling the electromagnetic consumer to ground and the voltage source, respectively;
- and
- triggering at least the second switching element of the half-bridge circuit such that energy is exchanged between the electromagnetic consumer and at least one of the energy-storing element and the voltage source.
