Dead-time effect caused by the switching lag-time, which avoids the phase shortage of inverter arms, causes serious distortions of output voltage and current of the inverter. In order to reduce the output waveform's harmonic content of inverter and the torque ripple of motor, several methods have been proposed. However, most of those methods consider from voltage or current compensation, and the relative realization are complicated meanwhile the result is not satisfied. With Fourier Transform this paper presents the principle of the dead-time influence on the torque ripple of the motor controlled by PWM inverter. By calculated, this paper obtains a set of optimal solutions. A novel method to improve the torque ripple was proposed. Theory analysis and simulation results show this method can decrease the scope of unreasonnable torque ripple.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125226212","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}

Therefore, this paper raises a distributed generation system (DGS) based on various renewable energy resources, adopting a small-sized combined generation equipments of unit capacity 100kW max with wind, solar and biogas energies, and super capacitor and battery storage devices, which builds and installs near to the local loads center to supply it optimally in stable and safe, high reliability and less feeder loss mode.

The active synchronization control strategy of motor is analyzed, which indicates that it has advantages and disadvantages. In order to solve the disadvantages, the control strategy of shifting without clutch operation for a DCM (Dynamic Control and Management) system is proposed. Based on the dynamic model of vehicle power train, the shifting process without clutch operation is studied. The off-line simulation model of the DCM system is built with Matlab/Simulink. Through offline simulation, the up shifting process and down shifting process of AMT are simulated. And the shifting time of various stages of shifting process is discussed. The off-line simulation results indicated that the shifting strategy without clutch operation is better than the active synchronization control strategy of motor.
