... treatment system is needed. The AMF requirements for this research present challenges to the design and manufacture of an induction system because a high flux density field at high frequency must be created in a relatively large volume. Additional challenges are presented by the requirement...

...TianQuan James Deng; Tang Ying; Li Wan‐Qing Purpose The purpose of this paper is to introduce trench termination for high power buried‐gate static induction transistor (SIT) comprising three parts, which can inhibit the reverse leakage current substantially and paradisaical current. The simplified...

.... In its most general form, the signomial program calls for minimising the total mass (or cost) of the inductor whilst ensuring the satisfaction of the inductance value together with constraints imposed by the copper fill‐factor, the allowed temperature rise, Kirchhoff's mmf law, and the core flux density...

...Ahmed Masmoudi; Fatma Ben Salem; Ahmed Masmoudi Purpose This paper aims to discuss a comprehensive analysis of the effects of torque and flux hysteresis bands on the inverter average switching frequency considering an induction machine drive under the control of the Takahashi DTC strategy...

... The comparison is based on three comparison criteria: the total harmonic distortion, the switching loss factor, and the quality factor. The comparison is extended to the FFT of the phase currents and to the analysis of the ripples of the electromagnetic torque of the induction motor. Findings It has been...

The paper gives an overall view of the workflow and the implemented mathematics, starting off with the two‐dimensional, transient electromagnetic simulation...

... for the induction motor with a stator core made from amorphous iron it is necessary to apply the circuit method and the field‐circuit method. The use of the circuit method allows quick calculations of many versions of the designed motor, but the use of the field‐circuit method is necessary for verification...
