Fundamental Behavior of Ternary Pulse Output Type FOC

The magnetization curve of a Ferrite Orthogonal Core (FOC) with excellent squareness ratio when the flux is controlled was studied for a new A/D conversion function. It was demonstrated that the FOC output voltage could be processed as a ternary digital output, and plotting the relation between the period intervals of two pulses of the same polarity, of a positive and a negative pulse, and the control magnetomotive force showed that phase control of the pulses is possible.
