Circuit arrangement for driving an occupant protection system gas generator whose ignition process can be influenced by a magnetic field |
摘要 |
The disclosure describes a circuit arrangement for driving an occupant protection system gas generator whose ignition process can be influenced by a magnetic field; this is based on a switching control principle, with the load coil generating the magnetic field being itself used as a component part of the switching control. For a fast reduction of the magnetic field and thus for accelerating the ignition process, a resistor may by connected into the free-wheeling branch, which is bridged in normal operation. Alternatively, it is possible to effect a return feed of the energy stored in the coil into the self-sufficiency capacitor.
