The triductor

This paper describes the properties of the d-c premagnetized static-frequency tripler or triductor. It is shown that the triductor has many superior properties as compared with the static frequency tripler of conventional type. The automatic or manual control of the saturation of the individual iron cores by superimposed d-c magnetization makes a number of applications practical. Of particular interest are the uses of the triductor as a static frequency transformer with regulated output voltage and its application as a highly voltage-sensitive amplifier.
