LOAD DRIVE DEVICE FOR INTERNAL COMBUSTION ENGINE

Title:

LOAD DRIVE DEVICE FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JP2007321713

Kind Code:

A

Abstract:

To stably dive both of an alternating current load and a direct current load.

Positive polarity side voltage of alternating current voltage induced by an exciter coil 11 is taken out by a diode 12. An ignition capacitor 14 is charged based on the voltage, negative polarity voltage thereof is taken out by a diode 13, and a power source circuit 30 is charged based on the voltage. Electricity is supplied to an ignition timing control circuit 20 by electric energy charged in the power source circuit 30. Electric charge accumulated in the ignition capacitor 14 is discharged based on ignition signal output from the ignition timing control circuit 20, and spark discharge occurs in a spark plug.
