CD IGNITION WITH ISOLATION CIRCUIT TO PROVIDE IMMEDIATE RECHARGING OF THE CHARGE CAPACITOR ABSTRACT OF DSCLOSURE Disclosed herein is a capacitor discharge ignition system comprising a charge capacitor, an ignition coil primary winding, an ignition SCR, and an isolation circuit connected in circuit with the charge capacitor, the primary winding and the ignition SCR. The isolation circuit preferably comprises a thyristor having an anode, a cathode, and a gate, and having an anode-cathode path connected in series relationship with the charge capacitor, and a parallel RC network having one end connected to the thyristor anode and having an opposite end connected to the thyristor gate. The isolation circuit is operative for selectively isolating the primary winding and the ignition SCR from the charge capacitor to provide for immediate recharging of the charge capacitor after the charge capacitor has discharged through the primary winding to effect an ignition spark.
