Application of an auto-parametric circuit for controlling thyristor converters

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