Abstract
PURPOSE:To simplify a circuit to control a main SCR by a method wherein a gate control signal is generated according to the positive and negative of ynchronous voltage using an integrated circuit and make it as a double pulse by a diode matrix. CONSTITUTION:A lamp wave having a 180 deg. cycle in an integrated circuit V by a synchronous signal from a transmission 50, and the gate control signal having the prescribed phase that compared it with the voltage at a speed setter 54 is output from terminals 14, 15. Next there to, these signals are made as the double pulse having a phase difference of 60 deg. againt respective terminals G1-G6 at a diode matrix M, and is amplified in an amplifying AMP to control thyristors 1-6 composing the pure bridge circuit during a DC motor 7. Accordingly, along with the mutual interference by the noise by individualizing the pulse transmission, the simplification of circuit can be designed.
