Controller for thyristor transducer

Abstract

Abstract PURPOSE: To eliminate the deterioration and unstable phenomenon of response generated in case of interruption, by making gain up to DC from phase control signals constant even in either of the continuity or interruption status of currents. CONSTITUTION: A secant transducer 10 secant-converts phase control signals VR, and puts out a set control angle α. The set control angle is inputted to a computing element 11 of a correction coefficient, and the correction coefficient K 1 is obtained. The product of a main circuit constant K from a multiplier 12 and motor currents Ia and the correction coefficient K 1 are multiplied by means of a multiplier 13, the output is inputted to a function generator 14 and a deviation angle θ is acquired. An adder 15 addes the set control angle α and the deviation angle θ, and provides a thyristor transducer 3 with ignition pulses through a gate output circuit 20. COPYRIGHT: (C)1980,JPO&Japio
