Abstract

In order to minimize the overall size of a firing capacitor and to minimize the energy which is not utilized during a firing operation, the firing capacitor charge voltage U.sub.0 is set to be equal to 2*R*I, where R designates the internal resistance of the firing cap and I designates the firing current. The capacitance value C.sub.0 of the firing capacitor is set to C.sub.0 =T/R, where T designates the period for which the firing current flows.
