Protection circuit for magnetically controlled d-c to d-c converter

摘要

A push-pull d-c to d-c power converter which is regulated by a magnetic amplifier utilizing pulse-width modulation to control the switching elements. The circuit provides stable operation by utilizing separate control windings in the magnetic amplifier for the voltage regulation and the over-current protection. In addition, symmetry control of the switching elements may be integrated with the voltage regulation by the addition of auxiliary control windings to the magnetic amplifier.
