Abstract :
To make magnetic amplifier theory mathematically tractable, numerous analyses which have appeared in the literature employ assumptions leading to either ¿ampere-turn control¿ or ¿volt-second control¿ idealizations. While either set of assumptions leads to quite good prediction of operation for simple saturable reactors, both simplified approaches break down at several important points when extended to self-saturating magnetic amplifiers. The regions of inadequate correlation have been explored extensively in recent years in terms of ampere-turn control, especially for self-saturating amplifiers exhibiting simple time delay. However, the limitations of the more recent volt-second control approach1,2 have received relatively little attention, especially for amplifiers exhibiting only dead-time (i.e., so-called ¿fast-response¿ amplifiers).3¿5
