Abstract :
Several papers have been published on the correlation between the control characteristics of magnetic amplifiers and the magnetization characteristics of magnetic cores.1¿5 However, the approaches hitherto inaugurated on this subject of great importance have failed in elucidating the problem concerning the effect of control-circuit resistance (CCR) on the control characteristics of full-wave magnetic amplifiers, because of the lack of an appropriate understanding of the dynamic loop of the reactor core. In the case of the highly oriented magnetic core with rectangular hysteresis loop, the control-magnetization curve (CMC)6,7 coincides very well with the flux-control characteristics produced by direct-voltage reset.8,9 This experimental fact enables us to interpret CMC as the relation between the rate of flux change and the instantaneous magnetizing current.
