However, if the regenerating load changes suddenly, the delay in the motor current control causes the filter capacitor (FC) voltage of the traction inverter increases and may activate the over voltage protection. This paper proposes a damping control method to reduce the peak of FC voltage using the over voltage resistor (OVRe). The proposed method is verified by numerical simulation assuming an actual railway vehicle under the condition of load shutdown at the highest power region, as the worst case conditions. By means of this method, the OVRe can be effectively utilized to reduce the FC voltage spike that results in more saving the substation energy.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131692192","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}

In such small-scale DC power grid, individual line impedance between elements such as power supplies, batteries, and loads is very low because of short distance distribution. Moreover, reactive power cannot be utilized to control power flow in the DC grids unlike the AC grids. It causes that large current flows through the lines even by a slight voltage difference. Therefore, power flow controllers with abilities to realize extremely high-speed and high-precision power flow control are required in the small-scale power grid. In this paper, multi-level converters are applied as the power flow controllers and realizes high-speed and high-precision power flow in the DC micro-grid. In the multi-level converter, as the number of the output levels increases, the output filter can become smaller. This paper also presents how to design the LC filter considering the number of the output levels of the converter to satisfy a requirement of current ripple. It is experimentally verified that the multi-level converter with a smaller filter can realize the high-speed and high-precision power flow control under the condition of the low line impedance compared with the 2-level converter.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128459459","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}

In addition, it is necessary to use large capacity converter for bulk power transmission. Therefore, modular multi-level converter (MMC) is optimum as a large capacity converter. MMC composed of chopper cell is lower cost and loss than full bridge cell topology. However, chopper cell MMC doesn't have blocking function, so it is not possible to cut off the fault of the DC side. Furthermore, the blocking of DC fault is difficult because the DC systems cannot generate current zero-cross point such as AC system. The proposed circuit breaker can eliminate the fault of the DC side. This breaker generates a current zero-cross point by using the resonance current, generated by the LC circuit. In this paper, characteristic of the proposed circuit breaker is verified by simulations.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115850205","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}

These power supplies must offer low capacitive coupling, reduced complexity, as well as low material and manufacturing costs. A six-output resonant converter is proposed which consists of a single half bridge and six separated transformers with individual resonant capacitors to minimize the coupling capacitances. The converter is operated at a fixed switching frequency without pulse-frequency modulation or duty-cycle control. Thus, the need for controller and output-voltage feedback is eliminated which results in minimized component count, reduced complexity, and low manufacturing costs. The resonant tank is analyzed and designed for a load-independent output voltage at fixed-frequency operation which shows a good ruggedness against variations of the resonant-tank parameters. The concept is validated by measurements of a 45 W laboratory prototype for a HybridPACK™2 IGBT package.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115906901","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}

Besides the ability to control the welding current, the peak power demand at the point of common coupling of these welding systems should be as low and steady as possible, making an energy storage mandatory. Previous investigations showed, that a flywheel energy storage offers significant advantages in terms of cycle stability, volume and efficiency compared to capacitor-based solutions. This contribution describes the topology of a complete welding system including a flywheel storage and its design process. Unlike state-of-the-art systems, the proposed topology incorporates a storage and the ability of dynamic current control. This paper addresses the specific challenges of this application. On the one hand, system dynamics have to be superior to typical flywheel energy storages; on the other hand, the topology has to be compact and efficient. Finally, robustness and simplicity of the system are of great importance to be industry-tailored. Because of the systems complexity, computer based modeling is used to simulate system performance and to optimize relevant parameters such as flywheel size and speed, motor parameters, transformers leakage-inductance, capacity of DC-link capacitors, etc. with respect to the goals stated before. Using different computer-based modeling tools, a simulation of the overall system shows that the proposed topology is practical and meets the specifications regarding size, efficiency and system dynamics. Based on these results, suitable components are selected. A prototype of the last converter stage is built which confirms expectations regarding leg current symmetry, dynamics and switching performance.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116749151","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 proposed model, based on instantaneous power theory as well as switching functions concepts, permits to evaluate the oscillating voltage that appears on the VSC dc-side. The effect of the zero- and negative-sequence current components are considered on the dc capacitance calculation which consequently enables to size the dc capacitor accurately in order to keep the dc voltage ripple of each split capacitor under pre-defined limits.
