Abstract
i1 Although the wide spread of silicon controlled rectifiers during the la et deca de did COver many applications of ma gnetic amplifiers, yet these amplifiers did not loose their pOpularity in both industrial and military applications.
Magnetic amplifiers can still be considered as one of the main components used in control systems where severe condit¬ions exist. Their high reliability, robustness, radiation proof’, simple construction and low serviceability made them indispens¬ible in control systems working under hard service conditions
and vibrations where any competitor fails to meet these service re qui rements.
The present work gives a complete mathematical solution for the problem of detennination a core model for self saturating
magnetic amplifiers. The transfer characteristics of the ampl-
ifier is detennined as”s function of the Core model F.. The in:f1.-
is studied. The amplifier behaviour is studied taking into
uance of the amplifier circuitry upon operating hysts~esis loops
consideration the quantitative effect of cor:::: charac”:eristics
upon the transfer characteristics. Approxin~te soluJ~ion as well as exact solution of the output difference equation are obtained. The analytical core model R is derived DY comparing the result¬ing expression of the vol ta ge ga in using the core mo c31 with the correSponding expression using the approximate solution.
The p~ctieal applica~ions of the core model are shown mainly in the analysis and design of self saturating magnetic amplifiers-. A new design method is introd’..lced using the core
model R.
Experimental verifications are given. and discussed.
