A practical estimation procedure to obtain the adequate I-PD gains specified by logarithmic interpolation from some regulation points is established under conditions of extremely wide load ranges as the medical use X-ray high-voltage generator. High speed processing hardware for the digital feedback control scheme with 20 kHz sampling frequency are also discussed as well as programming guidelines.

After an introduction, the structure of this drive system is described using the example of a 3-star motor with three independent 3-phase windings in the stator which are phase shifted mechanically against each other. Based on the transient equations derived, a control structure is proposed. Special attention is given to the harmonics of the inverter output currents. They can reach a high level due to the interactions of the inverters allocated to the individual 3-phase windings, which are coupled to each other magnetically. The current harmonics determine the dimensioning of the turn-off capability of the inverters. The modes of operation with sinusoidal PWM and square wave mode with fundamental switching frequency are illustrated and compared to normal single-star drives. It is shown how the pulse patterns can be optimized in order to get the lowest possible current harmonics at a given inverter switching frequency and a given fundamental frequency. The paper concentrates on the motor side of the drive system.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"693 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124109495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed method has the following features, compared with conventional methods; (1) it does not need an additional output voltage control for parallel operation; (2) the impedances among UPSs are resistive so that the circulating currents caused by phase difference among UPSs have only reactive components; and (3) increase of software for parallel operation control is minimal.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127892007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such techniques have previously been difficult because of an insufficient electromotive force at motor starting and at low speeds, and a constant coil inductance irrespective of rotor position. Therefore, this paper proposes to paste nonmagnetic materials onto the motor's rotor surface and to measure the open-phase voltage change caused by the eddy current which flows on these nonmagnetic materials. The proposed method is shown to be very useful by experimental results.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129370818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In cycloconverter drives, the zero current periods, related to the changing of thyristor bridges, cause torque distortion, which impairs the performance of speed control. The proposed filtering system is used for accurate zero-crossing detection in order to shorten the mandatory zero current periods. The authors' filtering system combines a low-pass prefilter and an adaptive predictive filter making it possible to extract the sinusoidal primary signal from noise and disturbances without harmfully phase shifting the fundamental component even when the frequency or amplitude alters rapidly. The predictive filtering is performed at time-varying sampling rate, so that the relative frequency of the fundamental component remains almost constant.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130738271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
