An adaptive hysteresis band current controller is proposed to control the hysteresis bandwidth according to the modulation frequency, supply voltage, DC capacitor voltage and slope of the reference compensator current wave.

A Γ - Z source inverter that has been introduced recently has a very interesting feature: unlike the Trans Z-source inverter its voltage gain is increased by lowering its transformer turn ratio. The voltage gain in a Γ - Z source is very sensitive to transformer turn ratio, particularly when it approaches to its lower limit of one. Therefore it should be wound carefully and should be a safety margin to avoid triggering of unanticipated events. In this paper, it is shown that the voltage gain is increased significantly with combined the Γ - Z source inverter with the switched inductor voltage multiplier cell. The proposed inverter is analyzed and the voltage gain is obtained and is compared with a Γ - Z inverter. It is shown that the voltage gain for the proposed inverter is higher than Γ - Z inverter in any transformer turn ratio. The performance of the proposed inverter is verified with simulation results.","PeriodicalId":414407,"journal":{"name":"The 5th Annual International Power Electronics, Drive Systems and Technologies Conference (PEDSTC 2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115341987","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}

Conventionally, the droop control is adopted as a decentralized control method for power sharing in DC MGs. However, current sharing accuracy or voltage regulation deteriorates due to the effects of line impedances. In this paper, a new adaptive control strategy is proposed for DC MGs. In low load conditions, the output currents of the DGs are far from their maximum acceptable limits. Therefore, current sharing accuracy is not important. As load increases, the output currents of the DGs approach their maximum acceptable limits. Therefore, at high load conditions, accurate current sharing is necessary. In the proposed method, with increasing the load, the equivalent droop gains are automatically increased to attain more accurate current sharing. Simulation results are provided to verify the validity and effectiveness of the proposed method.","PeriodicalId":414407,"journal":{"name":"The 5th Annual International Power Electronics, Drive Systems and Technologies Conference (PEDSTC 2014)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127474575","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}

Using trial and error procedure, an appropriate neural network is employed and trained for modeling saturation using back-propagation algorithm. Several steady state and transient simulations such as short circuit and sudden changes in input quantities are done.
