Our research group has been developing consequent pole type axial gap motor with field windings for traction motor of electric vehicles. From the point of fuel economy and layout, smaller and lighter traction motor is required. It is profitable to increase operation speed for reducing the size of motor. It is necessary to suppress line to line voltage to achieve high speed operation, and we examined pole-slot combination. Moreover, as rotor’s outer diameter of axial gap motor is larger than that of radial gap motor, the strength of rotor should be considered. We studied the adoption of non- magnetic high tensile strength steel for rotor supporting component. Motor design and the result of spin burst test are presented and we confirmed the operation of target maximum speed and output power density can be possible.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"9 1","pages":"2796-2801"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79857678","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 paper proposes a BMS power architecture where at any given time, an isolated converter connects either a module or one of its constituent sub-modules to the vehicle auxiliary bus, where a 12V lead-acid battery is present. The converters operate in burst-mode with a period of 10 s to simultaneously balance the sub-modules and regulate the auxiliary bus voltage. The use of module and sub-module input modes to the converters enables the supply of high-power auxiliary loads without an increase in converter input current rating. Simulations of one rule-based and one variable-priority control algorithm, both using SOC as the balancing parameter, are shown over a 6 hour load profile and 5% maximum initial SOC imbalance, for a 4 kWh liquid-cooled battery module prototye. Measurements using the same prototype are shown to match the simulation results. The simulation and experimental results highlight the necessary trade-off, in the system control, between auxiliary bus voltage regulation and balancing rate.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"69 1","pages":"267-274"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83541283","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}

Their models are categorized into two types with PM arrangement. One is the motor that has the PM arrangement based on the original design of the conventional PM vernier motor, and the other is the motor with a spoke type arrangement of PMs, which we have previously proposed. Typical vernier motors have a short air gap length, but the one that is applied to the steel-wheel linear motor train requires a larger air gap length. The examinations find a result that in the motor with the conventional PM arrangement increase of the PM volume hardly contribute to increase of the thrust, but that in the motor with the PM arrangement of a spoke type has a good effect on increasing the thrust.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"21 1","pages":"2836-2841"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73719706","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 the case that the amount of power is limited in a closed network system, the consensus algorithm can be useful for sharing the limited power resource in the system. For example, we consider a power network consisting of one power source and N(≫1) loads. We assume that each load has a buffer that can store the power for driving the load. It is important to efficiently share the limited power from the single source. One possible way for sharing power is as follows. First, all loads are divided into several clusters. Next, the power source sends power packets to each cluster by responding to the feedback information on how much power is required by the loads in the cluster. If the power demand of one load exceeds the power supply from the source, the deficient power is accommodated by the consensus algorithm among the buffers within the cluster. We discuss by numerical simulations how to cluster the loads in terms of the balance between the cost for distributing power from the source and the performance of loads.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"25 1","pages":"3665-3669"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84349819","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}

For downsizing of high-frequency (HF) transformers in these converters, developments of HF output MC control methods are active. It is expected to improve efficiency by applying soft switching techniques for these converters. However, to achieve soft switching, phase difference between an output voltage and a current is required. As a result, output power factor decreases. In this paper, a relationship between soft switching conditions and output power factor is revealed. Considering this relationship, the authors propose a new MC control method to achieve soft switching and maximum output power factor. Additionally, this method enables to suppress the distortion of input currents and reduce ripple of the output current. Also, the MC can control the output current and instantaneous reactive power. The authors confirm that experimental results show validity of the method.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"355 1","pages":"2589-2595"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76416019","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}

Energy density and system efficiency can be largely improved since the capacitor size is reduced. In addition, energy storage devices can be integrated in the proposed topology and thus make it feasible for smart grid and marine applications.

In this study a half-bridge planar power module with Silicon Carbide (SiC) MOSFET bare dies was designed and manufactured for ultra-low parasitic inductance. The circuit structure was simulated and the parasitic inductances were extracted from ANSYS-Q3D. The values were then fed into LT-Spice to simulate the electrical behavior of the half-bridge. The experimental and simulation results were compared to each other and were used to adjust and easily extend the simulation model with additional MOSFETs for higher current capability. It was shown that the proposed planar module, with four parallel SiC MOSFETs at each position, is able to switch 600V and 400A during 40 and 17ns with EON and EOFF equal to 3.1 and 1.3mJ, respectively.

Nevertheless, an internal balance mechanism exists in the MMC thanks to the capacitor voltage balancing. It contributes to an even conduction loss dissipation among SMs, which is studied and revealed in this paper.
