Simulation technique is quite effective for the most optimized design of an induction-heated(IH) cooking appliance in which both electromagnetic field and thermal flow require to be controled. We developed the system of nonliner analysis for electromagnetic field and thermalfluid by finite element method. By this system it is possible to simulate the behavior of electromagnetic field which causes induced currents and the behavior of thermal fluid simultaneously. This paper presents the results of performance evaluation for the new IH rice cooker as one of the applications of this system.

This paper presents a sensorless control of IPMSM using an estimated axis error on the basis of an extended emf. In the sensorless control method using a rotational axis model, the approximated model is generally used, thus some problems exist in the sensorless control at IPMSM with a large saliency ratio. In this paper the use of a rotational axis model using an extended emf can accomplish a sensorless control on the basis of an IPMSM model without any approximation. Moreover to confirm the effectiveness of the proposed method this paper shows simulation results of some kinds of drive situations and IPMSMs with various saliency ratios.

The decentralization might be the mega trend toward the new social system for the next century. Especially, reorganization of the electricity business, first initiated in the UK 1989, has acceleratedly unfolded globally and trust into the stage of retailing competition in the UK and the US. In this paper, decentralization of electricity business around the world are surveyed. Further, rule-making among market players and technical requirements at open electricity market are touched on.

The first three-years test schedule in the Yamanashi Maglev Test Line has finished with satisfactory results at the end of March 2000. As is represented by the high speed runs at 500km/h, the test results proved the superiority of the superconducting Maglev system. This paper introduces the LSM drive system in the Yamanashi Maglev Test Line as an application of the Power Electronics Technologies.
