Abstract

PURPOSE: To prevent the variation of the lagging angle start setting rotation by providing a lagging angle circuit for detecting the terminal voltage of a capacitor repeating the charge/discharge with predetermined time thereby controlling the operating time of a semiconductor switching element.
CONSTITUTION: When the rotation of the engine is higher than the setting level, the output waveform 46a of a signal coil 5 will exceed over the trigger level of a thyristor 9 and conducted to the position (q) during the predetermined conduction time of the transistor 34 irrespective of the increase of the rotation, thereby the thyristor 9 is applied with the output waveform then triggered while being lagged by the differential angle θ5 between the point K' and q. The range of the lagging angle is from the negative side peak level of the output wave form 46a to the point crossing with the level K' which is two times that of the conventional one. The lagging angle is θ3-θ4 while the range θ3 where the thyristor 9 is not triggered is 180°×t2/t1 and the angle θ3 required for the constant time t2 will be proportional to the rotation. The angle θ4 will decrease with the rotation but will be approximately constant for the rotation higher than the setting level.
