Application and calculation of dielectric amplifiers on variable speeds in the schemes of electric drives and self-excited asynchronous generators.

Abstract

The electrical circuits using dielectric amplifiers on variconds for controlling the rotational speed of a DC motor, starting asynchronous motors with a phase and short-circuited rotor and stabilizing the voltage of a self-excited asynchronous generator are considered. A simple approximate analytical method for calculating dielectric amplifiers on variconds is proposed, which does not require complex graphical constructions but is superior in accuracy to the well-known graph-analytical methods for calculating such amplifiers.
