Typically, inserted-shunt integrated transformers have symmetric primary and secondary leakage inductances. However, bidirectional resonant converters typically operate more efficiently with different series In this paper, a new topology for an transformer which can provide tunable, asymmetric (series) inductances on the sides is presented. Two magnetic shunts, appropriate air gaps, are inserte...

The study introduces the detailed sequence of operations necessary to determine the selfand mutual inductances of power transformers from numerically simulated open-circuit and bucking experiments. Parameters of a welding style transformer are compared to those of a normal step-down transformer of equivalent ratings. The investigation identifies the different patterns of magnetic flux circulati...

This new approach is based on a determination of analytic expressions of the non liner inductances deduced by a new analytic fitting of the nonlinear B-H curve. We have validate this new approach using the high voltage circuit of the power supply for magnetrons simulated by MATLAB-SIMULINK® code at the nominal state using the ferromagnetic material SF19. The comparison between experimental and ...

This paper presents a new and precise mo del for different kinds of eccentric rotor of rotating machines based on polar signals concepts. Eccentricity faults in each static, dynamic and mixed cases cause that the non-uniform air-gap of machine be established. The applied model using polar signals for eccentric rotors have removed the usage approximations in two recent decays. Eccentricity coeff...
