Beschreibung
Zusammenfassung:	PURPOSE:To have a small-sized and lightweight ignition coil by permitting a DC booster circuit to generate two kinds of boosted outputs with different voltages and by supplying one of them to the primary winding of the ignition coil and the other to the secondary. CONSTITUTION:The secondary side of a transformer 14 is constructed so as to generate two kinds of boosted outputs +VA, -VB with different voltages. The number of turns in No.1 booster 19 to output the boosted output voltage +VA is selected so that the voltage +VA becomes several tens to hundreds volts, and this boosted output voltage +VA given out by No.1 booster 19 is supplied to the primary winding of the ignition coil 26. The number of turns in No.2 booster 20 to output the other boosted output voltage -VB is selected so that -VB becomes several kilovolts in minus to -10kV, and this boosted output voltage -VB given out by No.2 booster 20 is supplied to the secondary side of ignition coil through capacitors C3, C4 and coils L1, L2.
