The use of the magnetizing effect of even harmonics of a siliv amplifier in the electric drive of the MUS system - D.

Abstract

The features of the operation of an intermediate magnetic amplifier MUP in the electric drive system MUS-D are considered. The correction signal of the system due to the discrete nature of the output of the power amplifier MUS contains a variable variable component in the form of an even harmonic MUS, which under certain conditions can be used for additional biasing of the MUP, which allows extending the control range of the drive speed. Such conditions are the choice of the frequency of the power supply of the CBM and the parameters of the choke included in the stabilizing circuit. The evaluation of the magnetizing action of the variable component of the control signal of the CBM is performed using the pulsed dynamic characteristics of its cores. The results of experimental studies confirm the theoretical background. Ill. 4, bibl. five.
