Thyristor DC motor with frequency control.

Abstract

The thyristor system of automatic control of the DC motor speed is considered, in which the frequency-pulse method of controlling the thyristors is used, due to which the system turns out to be static with respect to the main disturbances: change in the engine load, voltage of the AC network, motor excitation current. It is reported that this system turns out to be static with respect to changes in the frequency of the AC network and the disturbances that act directly on the control system of the thyristor converter.
