Application of an auto-parametric circuit for controlling thyristor converters

Abstract

This article discusses the issues of excitation of second-order subharmonic oscillations, in circuits representing a two-core electro-ferromagnetic circuit with a capacitive load, in order to use it to control the states of thyristors, frequency converters. The stability of the solutions of the equations of the two-core chain is investigated. Recommendations are given for obtaining stable subharmonic oscillations of the order 1/2 f when using these circuits as a control element of thyristor frequency dividers by two.
