The ARCP converter is capable of true pulse-width modulation (PWM) control of each phase. The power circuit relies on the addition of an auxiliary triggered resonant commutation circuit or snubber to commutate the inductive load current from a main diode to an active device, allowing a zero voltage turn-off of the main devices. The auxiliary devices operate in a zero current soft switching mode, thereby requiring minimal current turn-off capability. The operation and control of the ARCP converter are discussed. Its performance is analyzed, and a simulation is presented. It is shown that the ARCP converter is capable of operation at elevated switching frequencies (10-30 kHz), high power levels (200-1000 kW), and high conversion efficiencies. the auxiliary devices will typically account for a 20% increase in the total silicon area of a three-phase power converter.<<ETX>>","PeriodicalId":185839,"journal":{"name":"Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131072720","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}

Cabbage or carrot protoplasts were used. Cabbage protoplasts could be moved by the optical pressure at 10 to 80 mu m/s. Using a parallel electrode system, the protoplasts were connected to form a pearl chain. An argon ion laser was then focused on one protoplast at the tip of a pearl chain. All the protoplasts were trapped at the electrode by the dielectrophoretic force. and only the protoplast irradiated by the laser could be separated selectively. Microinjection of 0.2-0.4 mu m latex particles to the cabbages or carrot protoplasts was made using optoelectrostatic micromanipulation. The latex particles were transported to the surface of the protoplasts inside a parallel-plate electrode system. Then a pulsed high voltage was applied several times to inject one latex particle attached on the surface of the protoplast. The injected latex particle could be manipulated inside the protoplast by the optical pressure. The experimental apparatus and the results are reported.<<ETX>>","PeriodicalId":185839,"journal":{"name":"Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134319425","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 rotor used is the single-layer, modified cage developed by A. R. W. Broadway and L. Burbridge (see Proc. IEE, vol.117, p.1277-90, 1970). The input and control circuits share the same stator coils. The operation of the machine is dependent upon spatial harmonics of the stator and rotor conductor structures; therefore, the spatial harmonic contents of the excitation and induced fields are determined. A design formula for minimizing low-order, undesirable harmonics produced by the stator coils is presented. The form of the field harmonics and their direction of travel with respect to the rotor are established. Based upon the physical interactions of the rotor fields, a novel steady-state equivalent circuit with two excitation sources is established, along with the form of the requisite coupling factors. Contributions of the harmonic fields to the instantaneous and average torques are considered.<<ETX>>","PeriodicalId":185839,"journal":{"name":"Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122532934","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}
