The scheme incorporates two step-up DC-DC power converters to modulate the DC link currents at the third harmonic frequency. The modulated currents are then reinjected on the AC side of the diode bridge rectifier. Simulation results for a three-phase, 208 V (line-to-line), 3 kW system are presented. The sensitivity of the interface to unbalances in various system parameters is included. Results from experimental investigations on a small-scale laboratory model are presented.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122018416","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 ABDM has a powerful instruction set and a high operating speed. It exhibits several features that are essential in complex on/off control applications, including forking, latching and unlatching of an entire input bank, outputting of either a scalar output or a vector output, looping, conditional looping, and nesting of subroutines.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126911683","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 vector pulse width modulation (PWM) techniques, both in the deterministic and random versions, were compared with the traditional sinusoidal PWM strategy. The achieved enhancement of the operation of the delta inverter has been documented by results of computer simulations and an experimental investigation of a laboratory model. The study confirmed the superiority of the vector PWM techniques over the sinusoidal PWM strategy for a delta inverter. However, the improvement in the operating characteristics of the inverter is not as significant as that witnessed in bridge inverters. The random version of the vector PWM technique results in radically better harmonic profiles of the output voltage and current than those with the deterministic version.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121548176","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 humidity sensing dielectric used for the sensor mainly consists of a cylindrical-pore-like alpha -alumina film formed by anodic spark deposition, with a dense amorphous alumina thin barrier layer at the pore base formed by reanodization. The performance characteristics of the sensor, e.g., humidity sensitivity, humidity hysteresis, temperature dependence, response time, reproducibility, and long-term calibration stability, were studied in detail. It was found that the sensor can be used for absolute humidity detection in the range from -80 degrees C to -10 degrees C frost point as well as for relative humidity (RH) measurement from 10% to 100% RH with very stable performance.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"51 Suppl 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127807056","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}
