Stability of the proposed observer is guaranteed easily, because it is based on a linear model of the motor. Sliding mode is applied for the current estimation. Under the sliding node, the order of the observer's error equation is reduced. This makes the stability analysis easier so that robust position and velocity estimations might be achieved by the pole assignment. Experimental results show that the proposed method is very effective.","PeriodicalId":373820,"journal":{"name":"Proceedings IPEMC 2000.

The PWM techniques have still faced a few problems of how to control the amplitude and the k/sup th/ order harmonic voltage wave. The harmonic generator using BSRG technique can be used as source and sink power characteristics in any kind of load in the power system. Therefore, the frequency and amplitude of the wave form obtained from this harmonic generator can be independently controlled in order to use for a study of how the harmonics affect three-phase induction motors or transformers. Finally, the nonsinusoidal voltage waveforms of the fundamental with the 3/sup rd/, 5/sup th/, 7/sub th/ and 10/sup th/ order harmonics at various voltage distortion factors (VDF) obtained from the BSRG technique are illustrated and discussed.","PeriodicalId":373820,"journal":{"name":"Proceedings IPEMC 2000.

The discussion begins with a general three-port representation of power supplies that provide PFC and voltage regulation. Based on this representation and a power flow consideration, a systematic procedure is derived to generate all possible minimal configurations. It is found that two basic converters are in general required for implementing any of the possible configurations. Among these configurations only a few have been known previously and used in practice. The various possible configurations are compared in terms of their theoretical efficiency.","PeriodicalId":373820,"journal":{"name":"Proceedings IPEMC 2000.
