초록

This paper proposes a new circuit for the CDI system to have a constant ignition power at the engine speed range of 500 to 7500 rpm and the battery voltage range of 12 to 16 volts in the 4-cylinder automobile. The proposed CDI system has a closed-loop with a PWM DC-DC converter controlled by the error signal between capacitor voltage and reference voltage. In order to decrease the capacitor charging time, the primary winding of ignition coil is made to be shorted during capacitor charging. An experimental suystem is fabricated and the results obtained thereof are found to be satisfactory.
