The rectifier only uses an ac-side current sensor. The voltage information required for the PFC control is obtained from the ac-side current and its derivative in the on and off durations of the switching devices. The control of the switching devices is based on a pulsewidth prediction technique. The power factor of the rectifier is more than 99% over a wide load range. A method for balancing the two output voltages is also considered. Furthermore, transient performance is shown and discussed for load variations. The rectifier is suitable especially for a half-bridged inverter that requires a dual power supply. The practicability of the proposed voltage-doubling rectifier is confirmed by simulation and experiment.","PeriodicalId":293242,"journal":{"name":"2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC)","volume":"40 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124404667","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 AW design can avoid the problem caused by the fixed back-calculation gain in the classical AW design, and prevent saturation withdrawing ahead of time or a unexpected large overshoot due to a larger or smaller back-calculation gain respectively. The new method of AW is compared with the classical AW design by simulation and experiment on application platform of permanent magnet synchronous motor (PMSM) servo system. A PI controller with the proposed AW design can decrease the overshoot with shortening the settling time of system step-response, which can be observed obviously in wide dynamic variation.

Specifically, there is described the configuration of a traction drive with a surface mounted permanent magnet synchronous motor controlled by a direct torque control algorithm which is supplied via trolley-wire LC filter from a dc catenary. Because input LC filters are naturally nearly undamped and dangerous voltage oscillation can appear in the circuit, a new method for dc-link voltage stabilization is proposed. This method uses model predictive control for correction of traction drive operating point (demanded motor torque) which leads to the capacitor voltage stabilization and hence, improvement of the drive stability. The proper function of the stabilization (damping) effect of the proposed method is evaluated by a special frequency characteristic measurement which we proposed particularly for traction drives connected to a dc catenary. This paper also offers a comparison of our approach with the most frequently used damping method in traction drives. The behaviour of the DTC controlled PMSM drive has been verified by experiments on a down-scale laboratory prototype of the traction drive with rated power of 10.7 kW as well as the frequency characteristics measurement of this drive has been performed and evaluated.","PeriodicalId":293242,"journal":{"name":"2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129062771","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}
