Various UPS topologies provide different level of power quality to the critical load. On-line topology provides the best protection, and it is often the preferred choice for larger UPS installations. This paper presents a single-phase multi-source on-line UPS with isolated battery charger. The proposed structure consists of a boost rectifier, an inverter, and Bidirectional battery charger that is integrated with a Photovoltaic (PV) system. In conventional UPS systems, the battery is charged during normal operation from the grid and discharged to supply the loads during emergency conditions. Operation of grid and PV system as sources in parallel, utilizes the energy that the PV offers, solves PV system fluctuations, and increases the overall accessibility. Furthermore, the performance of UPS is improved by the switching rectifier in the grid side. Isolation would increase UPS flexibility and ensures compatibility with the required safety issues. The basic principles of the developed system and control algorithms are discussed in detail. Performance of the proposed structure is analysed and confirmed using simulations in MATLAB/Simulink software.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133106823","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 noise reduction procedure proposed here is included three separate parts: (1) stator design parameters optimization, (2) rotor pole design shape optimization and (3) inserting some barriers in stator structure. To calculate the noise of the SRM required for each design, an electromagnetic-structural simulation model is developed with finite element method (FEM) using ANSYS finite element (FE) package. Implementing the three above-mentioned parts for an 8/6 SRM, simulation results are presented and the procedure proposed for noise reduction of the SRM is evaluated.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116169076","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 converter decouples the magnetizing port and demagnetizing port in the asymmetric H-bridge converter of the SRM in order to prevent current overlapping. Asymmetric H-bridge converter in SRM only has the ability to apply zero, positive, and negative amount of the DC link voltage. The proposed front end converter theoretically can regulate DC link voltage from dc link voltage to infinity while it protects the integrity of the ASHB. The demagnetizing voltage is a PWM pulse, which can reduce vibration and acoustic noise in the SRM. The z-source network also naturally works as a ripple filter and eliminates the need for capacitor in the input DC link. Also this converter has bidirectional ability, which can be utilized in the hybrid electric vehicle (HEV) application. A software simulation has been done to verify features of this front end converter in the SRM drive system.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121551951","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}

Towards this end, the DC-DC boost converter is modelled based on the state-space averaging method with possible uncertainty in its parameters and also considerable variation in the input voltage. By deriving the open loop perturbed transfer function, an unstructured uncertainty bound for the nominal system is presented. Next, two robust controllers (i.e., H2 and H∞) are designed to regulate the DC bus voltage in the presence of drastically variations in the input voltage, the input inductor, the output capacitor, and the DC bus load. Simulation results demonstrate that the proposed controllers are strongly robust against uncertainties and can be applied to a practical DC microgrid.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115542839","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}

A modified model predictive controller is proposed for this converter in order to appropriately track the reference input currents with minimum number of switching actions. In comparison to the classical PI controllers, which are widely used in this application, the proposed controller provides notable advantages such as elimination of additional modulation stages and improving the dynamic and steady state performance. Moreover, designing PI controllers and tuning their parameters is more difficult for a multi-input converter, compared to a single-input one, since the behaviors of the multi-input converter input currents are not independent. However, the conventional predictive control scheme will result in ripple components due to its variable switching frequency performance. Therefore, some modifications are made in the design procedure to overcome the aforementioned problem of the conventional predictive scheme and improve the converter efficiency. Finally, the performance of the designed controller is verified and compared with the conventional predictive control scheme through simulation in MATLB/Simulink environment.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115927074","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}
