By employing an improved switch cell, ZVS for all the main switches is achieved without additional current or voltage stress. The zero-current-switching is also provided for the auxiliary switch. In all modes of operation of this converter, the input current flows through only two semiconductors. Therefore, conduction loss of this converter is as low as the conventional parent converter. With these features, the efficiency of the proposed converter is very high. A 500 W prototype is designed and simulated to verify the system performance.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131742131","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}

Water desalination is a solution that can be used to solve the water shortage problem. Capacitive deionization (CDI) is an effective water desalination method. CDI offers relatively low energy consumptions and low initial costs. This paper improves energy exchange between CDI units used in efficient CDI systems. Traditionally, hysteresis control is employed for transferring energy through power converters; this control method induces switching losses. Converter losses cause CDI systems not to operate in nominal voltage. In this paper, a buck converter and a CDI selector are proposed to compensate the losses. The maximum switching frequency is limited to prevent high switching losses. Simulation results validate the proposed scheme.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131139265","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 system includes a super-capacitor (SC) and a DC-DC convertor.

First the structure of the metro network is introduced, then the model of ESS and its control strategy are explained. An important feature of this simple and effective control strategy is the use of appropriate reference current for charging and discharging of SC. Simulation in MATLAB/Simulink showed that DC bus voltage fluctuation is limited, which is acceptable, and the super-capacitor voltage changes are kept within the allowable range and total input energy of substations is reduced considerably.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116933150","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 primary challenge with the single-phase rectifiers is the input alternative power with twice the grid frequency, which should be filtered out properly. The lack of proper filtering leads to significant second-order voltage harmonic at the charger output. This results overheating and decreasing of the battery lifetime and performance. In this paper, an active method to filter out the second-order voltage harmonic is proposed. In the proposed method, the input alternative power of the charger is absorbed by an inductive auxiliary energy storage element. Using the proposed method, the size, weight and implementation cost of the charger are decreased, as well as its power density and reliability are increased.

The proposed converter provides an extended duty cycle for switches and also, the voltage stress across two switches and two didoes is one fourth of the input voltage and for the other semiconductor elements is smaller than half of the input voltage. This voltage stress is much lower than that of conventional interleaved buck which makes it possible to use switches and diodes with lower voltage rating. As a results both switching and conduction losses, can be reduced and consequently the overall efficiency can be improved. Another advantage of the proposed converter is its extremely low output current ripple which requires an additional small inductor. All these benefit are obtained without applying additional stress on active components or using transformers. The simulation results based on a 480W, 400 to 48 V dc/dc prototype verify the effectiveness of the theoretical analysis.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127484913","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}
