In this paper, the relationship between material and the flux control characteristic of a ferrite orthogonal core (FOC) as a measurement and control element, is presented.
Five types of materials are examined to know the difference between their flux control characteristics. Results show that the material which has higher amount of saturation flux density can make its flux control amount bigger.
It is clear that the higher rectangular factor material has the larger amount of flux control. Furthermore, the material which has low loss but high saturation flux density shows good linear flux control characteristic. FOC which has good rectangular factor and high flux sensitibity is useful for measurement control element, especially for the on-off activity.
