To improve the output quality of multilevel converters, different modulation techniques have been suggested in the literature. The most suitable modulation technique for high-power high-voltage applications is selective harmonic elimination (SHE) due to having fundamental switching frequency. In this paper, a simple method for elimination of low order harmonics in nine-level CHB converter is proposed. Using this technique, there is no need to solve complex trigonometric equations and therefore, this technique can be implemented in real time using a simple processor. Furthermore, all CHB modules operate at the fundamental switching frequency and power consumption is shared identically among them. To demonstrate the validity of the proposed method, simulation for a three phase nine-level CHB inverter is presented.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124371606","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 enhancing speed control in acceleration mode is like magnifying the brake performance. The goal of both speed control system in acceleration mode and braking system, is reducing the time duration of speed changes. Braking control systems is common between, cars, trucks, motorcycles, trains, etc. For this reason several project to improve the performance of the braking systems have been done. The most famous of this advances is Anti-lock Braking System (ABS). The base of ABS, is using the maximum of the friction between tire and road surface. In order to reducing energy consumption, train wheels and rails are built from iron. Since wheel and rails are built from iron, the friction between them is weak. Hence when the propulsion system tries to push forward the train, the driven will began to rotation and the speed of the driven wheel is more than the train actual speed. The name of this phenomena is wheel slip. As described in this paper wheel slip has a significant impact on the adhesion between wheel and rail. In the other hand train acceleration is function of the adhesion between wheel and rail. Therefore in order to improve the train acceleration, the maximum of the adhesion should be utilized. For these reasons in this paper a hardware simulator to implement and test the adhesion control methods is proposed.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114191439","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 important advantages of the proposed converter are as: Only one active switch is required without extreme duty cycle that high voltage is attained, The voltage stress on the active switch and diodes are reduced by increasing the turns ratio of the secondary windings of the coupled inductor, and the energy of the leakage inductance of the coupled inductor is recycled by switched capacitor and directly transfers to the load. The operation principle and steady state analysis of continuous conduction mode are used to determine voltage gain and switch voltage stress. Also the extension of the proposed converter to attain more step-up voltage gain are presented. The simulation results are used to verify the performance and validity.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129163603","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 paper presents multiband hysteresis modulation to Field Oriented Controlled (FOC) IPMSM fed by a 9-level asymmetrical Cascaded Half Bridge (CHB) inverter. For this reason, hysteresis controllers have 9-band current error. The CHB is more attractive choice due to its modular structure and higher number of output voltage level for the same number of semiconductors in comparison with symmetrical CHB. The results show several advantages of this method such as high accuracy, fast dynamic response, insensitivity to parameter variations and simple implementation.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130805496","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 goal is to improve the transient response and reduce the harmonic distortion, as well as size and cost reduction of the input filter. Since the proposed method is sensorless, the AC line voltage sensors are eliminated and the virtual flux block would be used instead. The cost and size of the filter could be reduced since the LCL-filter has lower inductance values and also the harmonic distortions could be reduced as well. The only drawback of the LCL-filter is producing resonance oscillations due to the resonance frequency of its third-order transfer function. In order to eliminate the oscillations, a simple method of active damping is utilized. Finally, simulation results have shown an excellent dynamic response compared with a three-phase converter that uses a conventional L-filter.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115095649","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}
