Abstract
A device for supplying an ignition current from an energy reserve to at least one ignition power module, a voltage regulator being provided between the energy reserve and the at least one ignition power module, setting a voltage on the at least one ignition power module at a predetermined level.
Claims6
A device for supplying an ignition current from an energy reserve capacitor to at least one ignition power module, comprising:
- a voltage regulator connected to the energy reserve capacitor by a polarity reversal diode and at least one current source, the voltage regulator being directly connected to the at least one ignition power module such that the voltage regulator sets a voltage at the at least one ignition power module at a predetermined level;
- and
- a control module which selectively triggers the voltage regulator to alternatively operate as a safety semiconductor.
Dependencies are inferred from the claim text.
