Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

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 order1/2fwhen using these circuits as a control element of thyristor frequency dividers by two.
