Circuitry for Magnetic AmplIfier Freed
from Triggering

Tamiya NARUSE, Sigeru OYAMA

In a magnetic amplifier operating on the condition of the under-excitation voltage, the phenomenon called ("triggering" happens occasionally at the minimum load point of the magnetic amplifier, and this phenomenon is harmful to the normal performance of magnetic amplifier operation in a system. This paper presents the circuitry for a magnetic amplifier freed from "triggering" and describes the experimental results.
No triggering happens, if the magnetic cores are prevnted from the excessive resetting in the over-controlled condition. And, as an effective means for this pereventation, zener-diodes are used in the circuitry and the varisters are interconnected to support the desirable performances of the zener-diodes whenever the supply voltage is changed. The control characteristics are compared with those of the bared magnetic amplifier; and the calculated optimum characteristics are examined with the experimental results.
