摘要： PROBLEM TO BE SOLVED: To simplify the circuit while stabilizing the trigger circuit for a thyristor by counting pulses based on a vehicle speed measurement signal synchronized with the voltage generated from an exciter thereby generating a trigger signal for the thyristor. SOLUTION: An AC voltage generated from an exciter 1 is rectified through a half-wave rectifier circuit 31 and a zero-cross point thereof is detected through a zero-cross detection circuit 32 in the next stage. It is then shaped through a shaper circuit 44 to produce a vehicle speed measurement pulse synchronized with the AC voltage of the exciter 1. The pulses of vehicle speed measurement pulse synchronized with the AC voltage of the exciter 1 are fed to a CPU 40 and counted at the counter section 42 thereof. Since the vehicle speed measurement signal is synchronized with the AC voltage of the exciter 1, the circuit can be simplified and trigqer of the thyristor is stabilized thus stabilizing operation of the system.
