Thereby, the maximum value of an output voltage from the AC generator 1 is kept always above, for instance, 7V, and by inputting this output voltage directly to the DC-DC converter 6 without through a regulator circuit 2, a sufficient ignition voltage is obtained to enable engine start.;...
5 of a current detection type DCCDI type ignition control device, output energy of the DC-DC converter 5 to an input is decreased bit lowering of the generating voltage of an AC generator 1 and a weakening battery 3 is prevented from occurring, resulting in improvement of starting easiness....
providing first and second secondary winding wires for ignition and timing control, both wires being wound in identical directions opposite the directions of primary winding wires, and a voltage smoothing circuit between the second secondary winding wire and the timing control circuit in a DC-AC ...
