The turn-on and turn-off transitions of the switch are zero voltage switched resonant transitions. Two saturable cores operated in minor B-H loop are used to achieve such transitions. The waveform of the voltage across the switch is trapezoidal, and the current flowing in the switch is a quasi-square-wave. The switching losses are considerably reduced, and the stresses in the switch are significantly suppressed. The converter has load characteristics similar to those of a square-wave pulse-width-modulated (PWM) forward converter. The on duty ratio is modulated by a small current applied to the winding of one core. Experiments on a 350 kHz, 100 W DC-DC power converter show good performance.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114521125","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 achieves soft switching without increasing the voltage or current ratings of devices and has the capability of HF and four quadrant operation. HF operation by soft switching provides several advantages such as high power density, low electromagnetic interference and high dynamic performance. The voltage stresses and the current stresses in this converter are limited to the supply voltage and the link current by the operation of a current free-wheeling circuit, and thus the VA ratings of devices are reduced to those of the hard-switched inverters. Simulation results are presented to verify the operational principle.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129584041","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 method shows that a single polynomial can be defined to eliminate a very large set of harmonics. Transcendental equations obtained in PWM waveform harmonic elimination using Fourier series of linear algebraic equations using Walsh series are replaced by linear block codes. One generator vector may cancel unwanted harmonics. The software is very simple; memory requirements are greatly reduced; and advances in microprocessor technology and speed make this mmm most advantageous for harmonic elimination in real-time systems.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129229043","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 method is based on estimating the instantaneous SR motor torque from the flux linkage versus current and rotor position characteristic curves via a bi-cubic spline interpolation. These coefficients are computed offline, stored in a given memory location of the control processor, and used by two routines that are capable of estimating the rotor position and electromagnetic torque from the phase voltages and currents. The estimated output torque is then compared to a constant reference value, and the result of this comparison drives a current regulator that generates the proper motor phase currents. The ripple minimization scheme is simple and does not require a very fast processor. Its feasibility is confirmed via simulation and some preliminary experimental results.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121955599","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}

This is probably based on the intuitive feeling that switching pattern discontinuities dead-band-degrade the quality of output/input voltage/current waveforms by introducing low-order harmonics. The authors challenge this notion by showing that discontinuous switching patterns for PWM converters can yield better performance than their continuous counterparts. Performance is defined as harmonic distortion normalized with respect to switching frequency, and serves as a measure of comparison with continuous PWM techniques. The applications considered include general-purpose and application-specific solid-state power supplies utilizing voltage current inverters and PWM synchronous or buck-type rectifiers. Theoretical considerations are verified on an experimental unit.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131922095","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}
