In terms of the switching frequency of high power converter, there can be harmonics interruption if the voltage source converter has a low switching frequency ratio or multi-sampling frequency. The range of the control bandwidth can include the switching component. Thus, the systems become unstable. This paper applies the Harmonic State Space (HSS) Modeling method in order to find out the transfer function for each harmonics terms. The modeling procedure shows the precision in the analysis of the stability as well as the controller design.

The inverter stage of the new IMC topology is composed of five legs instead of the conventional six legs for the three-phase open-end winding load applications. The SVM method to drive the five-leg IMC is developed to operate the inverter stage as two independent three-phase inverters with five legs. The proposed configuration has the advantages such as sinusoidal input/output current waveforms, ability to boost voltage transfer ratio up to 1.5, and zero common-mode voltage across the open-end phase windings; its performance is not deteriorated compared to that of the six-leg inverter in spite of the reduced leg. Simulated results are presented to verify the effectiveness of the proposed topology and its SVM method.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128018208","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 PCS should supply the power to the critical load, regardless of the grid condition. In order to provide the power to the critical load continuously, the PCS should operate two modes. One is Grid-Connected mode and the other is Stand-Alone mode. It is important to know the grid condition to decide operation modes. This paper proposes a control method based on the grid frequency to detect the grid condition and consists of a current controller and a feedforward voltage controller. The grid frequency detection is able to reduce the grid fault detection time and a feedforward voltage controller helps voltage regulation fast. This proposed control strategy is verified by the simulation and experimental results.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115857443","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 efficiency of MMC stations are highly related to the switching methods and semiconductor devices. So, various switching methods and semiconductor devices have been investigated and introduced in the field. This paper settles a benchmark for an HVDC link, based on a real project, and investigates the impact of six different switching methods on the converter loss, utilizing a commercial semiconductor device. The evaluation indicates that switching methods which consider the current level at switching instants are more efficient in comparison with the other methods which only consider the number of switching events. The result of this study is essential for more efficient converter stations.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"17 22","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132546544","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}

DC current injection into ac grid severely affects distribution system components such as isolation transformers, measurement units and protective relays. The proposed dc current offset compensation technique exploits a simple proportional-resonance (PR) controller that aims to suppress dc offsets to zero in the output currents of grid-connected inverters before entering the main 50/60Hz interfacing transformer. By employing this technique, the capital cost of a medium-scale solar farm is reduced since it enables transformerless operation of all inverters within the farm, and uses only one power transformer at point of common coupling. Additionally, this technique does not rely on high-precision current measurement devices nor uses any form of complex transformer. Simulation and experimentation are used to demonstrate the practicability of the proposed system.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129973660","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 single-switch voltage equalizer using multi-stacked buck-boost converters can significantly reduce the necessary switch count compared to that of conventional topologies, achieving simplified circuitry. However, multiple current sensors are necessary for this single-switch equalizer to effectively perform equalization. In this paper, a current sensorless equalization technique, ΔV-controlled equalization, is presented. An equalization strategy using the ΔV-controlled equalization is explained and discussed on the basis of comparison with other equalization strategies. Experimental equalization tests emulating partial-shading conditions were performed using the single-switch equalizer employing the ΔV-controlled equalization. Negative impacts of partial-shading were successfully precluded, demonstrating the efficacy of the proposed ΔV-controlled equalization strategy.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130249926","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 system is comprised of a line frequency transformer connected to a power electronic converter that is `auto-connected' on the secondary side. The auto-connection is facilitated by the use of a high-frequency (HF) / medium frequency (MF) transformer. A simplified strategy to compensate for voltage sags, swells, and distortions on the grid side, by providing continuous ac voltage regulation, is discussed. When a voltage disturbance event occurs, the power electronic converter generates a compensating voltage, which is vector-added to the grid voltage in order to regulate the output voltage supplied to the load. The smart distribution transformer will satisfy the various needs of the present and future distribution smart grid such as improved availability, equipment protection, and resilience. This paper provides detailed analysis, simulation results and experimental results from a scaled down laboratory prototype rated 200 W are also presented to validate the operation of the proposed smart distribution transformer.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133883698","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}
