The simplest and most versatile form of bearingless motor is the bearingless slice rotor motor. This kind of motor with centrifugal pump has a wide range of applications in life science, chemical processing industry, semiconductor manufacturing industry, foodstuff processing industry, and so on. In the paper, a 3-phase permanent magnet slice rotor motor is set up, and suspension principle of bearingless permanent magnet slice rotor motors is introduced. Theoretical formulas of driving system and radial suspension forces are given, and then the control system for the 3-phase bearingless permanent magnet slice rotor motor is designed and presented. An experimental platform of digital control system is developed to meet the need, and experiments including core loss measure, speed regulation and suspension force control are performed. The experiment results are presented under unload and load. The experiments have shown that the vibration amplitude in x- and y-direction is less than 200 mum under unload and load, while rotor speed are changed from 0 r/min to 8000 r/min","PeriodicalId":448315,"journal":{"name":"2006 CES/IEEE 5th International Power Electronics and Motion Control Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121806045","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 gate driver for each power semiconductor requires its own floating or isolated DC voltage source. Traditional methods on meeting the requirement are expensive and bulky. This paper presents a gate driver design for floating voltage source type multilevel inverters. Bootstrap capacitors are used to form the floating voltage sources in the design, which allows a single DC power supply to be used by all the gate drivers. Specially configured diode plus the proper charging cycles maintain adequate capacitor voltage levels. Such a simple and low cost solution allows user to utilize the easy accessible single-channel gate drivers for multilevel inverter applications without the extra cost on the bulky isolated DC power supplies for each gate driver.

The operation principle of the very converter is simply analyzed. Digital design consideration based on the small-signal dynamic modeling of the isolated PFC converter is specified in this paper. Implementation strategy and cost effectiveness of digital control for the single-stage PFC converter are studied. A transformer is used to provide galvanic isolation enables a wide range of output voltages, either lower or higher than the input voltage, allowing multi-output solutions. The adopted digital control strategy features fast dynamic response and excellent steady regulation characteristic without multiplying the input feedforward. High power factor and high efficiency are both achieved by combining FB main circuit and digital control. That flexibility is greatly increased can further contribute to system integration research on distributed power system. Without multiplying the input feedforward, fast dynamic can be achieved due to the flexibility of digital control strategy. The above excellent performances are verified by an experimental prototype, whose output power is 3 KW and PFC operating frequency is 110 K","PeriodicalId":448315,"journal":{"name":"2006 CES/IEEE 5th International Power Electronics and Motion Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130464006","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}

Comparing with the traditional transformers, it has a special magnetic structure, namely magnetic air-gap shunt, and adds a resonance coil on the secondary side. The modelling and analysis indicate that the magnetic air-gap shunt can be equivalent to a step-down inductor between the primary and secondary coils. It is in series with the parallel resonance-circuit to construct a filter-network, which makes the difference-mode (DM) interferences be attenuated obviously, while nearly doesn't affect the fundamental signal. In order to suppress the common-mode (CM) interferences, two coils with few turns and opposite direction, which are in series with the primary coil, are also added.
