Abstract (en)
[origin: JPH03149351A] PURPOSE: To permit ignition in a short time and adjustment of combustion duration by connecting an energy return diode in parallel with the capacitor of a primary circuit, and controlling the primary circuit by use of a control and adjustment device sized to operate in current-controlled shutoff operation and in current-carrying operation. CONSTITUTION: A primary vibrating circuit has a control and adjustment circuit 2 having a trigger input end 4, a trigger output end 6, a power conductor 8, and the primary circuit winding P1 of an ignition coil. A vibrating circuit capacitor C1 is in series with the primary circuit winding P1 and an energy recycling diode D1 is in parallel therewith. A transistor TR1 is connected to the capacitor C1 and the diode D1 at its drain side and to earth at its source side via a current limiting resistance R1, and a connection 10 connects the transistor TR1 to the resistance R1 and the control and adjustment circuit 2 on the source side. On the secondary side, a secondary winding is located in series with the winding and a discharge capacity CW.
