Abstract
An electronic ignition system includes a converter for receiving DC power from a source of DC power such as a battery. The convertor converts the DC power at low voltage to a high frequency signal which is stepped up to provide a higher voltage to a charge storage device such as a capacitor. The higher voltage on the capacitor is then made available to an ignition coil under the control of a microprocessor or a microcontroller for providing high voltage electrical energy to one or more spark plugs of an internal combustion engine.
Claims15
An ignition control system for use with an engine ignition coil for receiving voltage within a predetermined operating range, comprising:
- an electrical input for receiving a direct current voltage from a power source;
- a convertor connected to the electrical input for converting the direct current voltage to a predetermined converted high voltage by first converting the direct current voltage to a high frequency voltage and deriving a high voltage fron the high frequency voltage before applying the predetermined converted high voltage to the ignition coil;
- and
- a controller for regulating current available from the convertor to be within the predetermined operating range to allow the convertor to supply proper high voltage to the ignition coil.
