Abstract :
A new magnetic amplifier utilizing temperature dependence of coercive force is presented in this paper. Operations of the magnetic amplifier are explained well in an analysis based on a simple assumption. For amplifiers using temperature-sensitive Co-ferrite core, two useful control characteristics are obtained, one is that the load current varies linearly with temperature and the other is that it changes rapidly at the desired temperature.
