This relationship was investigated experimentally on both new motors, on a vibration stand and on a motor with berating wear. Both theory and experimental results show that a change in the RMS value of the stator current is directly related to the change in vibration magnitude, for a known vibration frequency. The paper shows this result both for a new motor with an externally induced vibration and for a motor with vibration caused by progressive bearing wear.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127277474","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}

Specifically, the merits and limitations of the constant-frequency (CF) continuous-conduction-mode, CF discontinuous-conduction-mode (DCM), variable-frequency DCM, and zero-voltage-switched DCM flyback power converters with synchronous rectifiers are discussed. The theoretical efficiency improvements of the discussed synchronous rectification approaches relative to Schottky diode implementations are derived.

The control scheme combines a variable volt/hertz ratio inverter drive and an average motor current regulation loop to achieve the control of the motor torque-speed characteristics, and consequently control of the air flow rate of the blower which the motor is driving. The controller is simple for implementation and practical for commercialization; it is also reliable since no external pressure or air flow sensor is required. Both theoretical derivation and experimental verification of this control scheme are presented in the paper.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114354472","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}

To achieve such a low height, full custom cores have been used, together with an advanced technology (flex foils) for the windings. This freedom in the selection of dimensions and materials makes the design procedure completely different to the traditional schemes with commercial cores. The process used to obtain an optimum design is described in this paper. It is based on the use of models based on finite element analysis (FEA) tools, and spreadsheets. This procedure has been applied to the design of a transformer and an inductor, with a size of 10/spl times/10/spl times/4 mm/sup 3/ for each, to be used in an onboard power converter in telecommunication systems. Experimental results of a 5 W, low output voltage (3.3 V/spl times/1.5 A) prototype with these magnetic components are included in the paper.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114581092","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 technique takes advantage of a modified Kohonen's competitive layer to calculate the on duration of the adjacent switching state vectors. By using this technique: (a) the hardware and software complexity of the system is reduced; (b) the maximum attainable switching frequency and thus the bandwidth of the control system is increased; and (c) the waveform degradation and parasitic harmonics resulting from inaccurate calculations are avoided. The proposed method is compared to the conventional implementations of SVM techniques in terms of hardware/software requirements, switching frequency, computation time, and harmonic spectra. The method is applied to a DSP controlled 3 kVA unit (voltage source inverter) and experimental results verify the validity of theoretical and simulation results.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132755280","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 converter operates with fixed switching frequency, and with a continuous input current that is sinusoidal and in phase with the input voltage. This is in contrast with most other single-stage converters, which are either resonant converters or must operate with a discontinuous input current. All converter switches operate with soft-switching due to a simple auxiliary circuit that is used for only a small fraction of the switching cycle. In the paper, the operation of the converter is explained and analyzed, and design guidelines are given. The feasibility of the converter is shown with results obtained from an experimental prototype.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133596640","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}
