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}

However, transformerless inverter topologies have a lot of advantages, such as low cost, light weight, small size and high efficiency, but their semiconductor devices are still on hard-switching state at present, which normally has low efficiency, since the power losses across the switching devices are high. In this paper presents a novel Zero-voltage-transition concept for a new full bridge neutral point clamped (NPC) transformerless inverter, which has soft-switching technique and low leakage current. The proposed topology unite two coupled inductor along with series connected switch on AC side that operate alternately in positive and negative half period of grid.

This converter was recently presented and it can provide high voltage gain and has current ripple cancelation ability at a preselected duty-cycle. The input current ripple is zero when the converter works at a special duty-cycle. But load disturbance leads to output voltage changes that maybe cause the duty-cycle to deviate from its preselected value. In this situation, the input current ripple cannot be completely canceled. The proposed proportional strategy is an optimized method for minimizing input current ripple at other operating duty-cycles and also it provides a voltage gain lower than conventional complementary strategy. Here, the converter's performance is analyzed under two switching strategies and the effect of various strategies has been investigated on converter parameters including output voltage and input current ripple. These considerations are verified by implementing a 100-W prototype of the proposed converter in laboratory.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"86 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":"115919265","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}
