Abstract
A method for controlling the trigger sequence in a flywheel magneto system including a magnet system for inducing a trigger pulse for a gate trigger current switch. When the trigger pulse is below a preset level N, the ignition system is triggered based on a voltage difference in the trigger pulse following the trigger pulse peak. As the rotational speed and amplitude of the trigger pulse increase, the triggering is advanced. When the trigger pulse exceeds the preset level N, the ignition system is triggered when the trigger pulse exceeds N. As the rotational speed and amplitude of the trigger pulse increases, the triggering is further advanced. A voltage threshold component is connected in series with the gate trigger current switch to avoid triggering interference.
