PESC Record - IEEE Annual Power Electronics Specialists Conference   Vol. 1, pp. 436-442(1) 436-442
This paper proposes a new series resonant DC link PWM inverter. The proposed inverter can have smaller inductance than the conventional series resonant inverter, and be also applied as soft-switched AC/AC or AC/DC converter easily. The output cont...

SPEEDAM 2010 - International Symposium on Power Electronics, Electrical Drives, Automation and Motion   1270-1275
Switched reluctance motors (SRMs) have some mechanically structural and electrical advantages. They also have disadvantages not only related to noise but also to nonlinearity in electromechanical responses. Unlike, for example, dc motors, the resp...

IECON Proceedings (Industrial Electronics Conference)   pp.1320-1325 1320-1325
High-performance as well as user-friendly circuit simulators are powerful aids for power electronics engineers. This paper presents a new circuit analysis and design simulator named TAP-T (Transient Analysis Program "TOKUZO") mainly for power elec...

2013 IEEE 14th Workshop on Control and Modeling for Power Electronics, COMPEL 2013   
This paper proposes new current control to reduce eddy current loss (ECL) in switched reluctance motors (SRMs). Motor parameters and flux density of SRMs are pre-calculated by magnetostatic analysis. Eddy current causes the change of the flux dens...

Electrical Engineering in Japan (English translation of Denki Gakkai Ronbunshi)   135 64-75
Generally speaking, the characteristics of induction motors (IM) are analyzed by means of the equivalent circuit with d-q transformation. Although this method is simple, the magnetic flux distributions in the stator and rotor are defined as sinuso...

Ministry of Education, Culture, Sports, Science and Technology: Grants-in-Aid for Scientific Research(若手研究(B))
Project Year: 2009 - 2010    Investigator(s): Hiroki ISHIKAWA
One of the most attractive merits of switched reluctance machines (SRMs) is they have no permanent magnet. The SRMs, however, have some demerits, large torque ripples, and nonlinear characteristics, especially. The torque ripples results acoustic ...
