An integral equation formulation is obtained for the solution of electric and magnetic polarization in the material body subjected to external excitations. Numerical treatment of saturable magnetic field problems is facilitated by the introduction of

An inverter using thyristors, commutated by small inductance and capacitance only, and having an output frequency range suitable for motor speed control, is developed. The circuit operates as the combination of a high-frequency inverter and a cycloco

A digital model for a three-phase induction machine is developed, which is particularly adapted for studying its dynamic performance when fed from an inverter. Conventionally, the induction motor is analyzed in terms of its d-q variables, while the o

Integral equations are shown to offer definite advantages over conventional finite difference techniques for solving magnetic field problems. In Part I of this paper two models are presented to account for the presence of a ferromagnetic medium. In t

A relay scheme has been developed based on the instantaneous phase current zero crossings. Transient and steady- state unbalances will produce shifts of the phase currents, therefore measurement of the deviation of successive zero crossings from 60 d

Induction machine instability is predicted on the basis of equivalent circuits. The circuits are derived assuming sinusoidal perturbation of the rotor speed. Classic rotating field concept is used in the analysis. It is shown that equivalent estimate
