However, various problems such as the burden of unbalanced loads, parallel operation of multiple inverters, and harmonics of the system voltage received from household electric loads can arise when constructing an MG in an emergency using a domestic single-phase three-wire (1P3W) system. Therefore, we introduce a new VSG method for 1P3W systems to address these issues. This method is based on the previously proposed VSG methods for three-phase and single-phase two-wire systems. In this paper, we demonstrate that a small-capacity inverter with two VSGs can stably supply electrical power to 1P3W home appliances.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"87 1","pages":"767-774"},"PeriodicalIF":0.0,"publicationDate":"2018-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88169982","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}

Moreover, the proposed converter can reduce additional conduction loss under the light load conditions without complicated control method.

In theory, reactor size can be reduced in proportion to switching frequency. However, practically, as the switching frequency is increased, the reactor is affected by the parasitic capacitance existing between the windings and between the winding and the core, and the inductance characteristic of the reactor is deteriorated. As a result, there is a limit to increase the switching frequency. This paper proposes two kinds of wire guides with two-layer winding and three-layer winding to reduce the parasitic capacitance. The effects of the wire arrangement and the material of the guide are also evaluated. With the proposed guides, the parasitic capacitance decreases by 0.73 times and 0.66 times compared with the conventional reactor. Moreover, the linear regions of the impedance which can be regarded as a pure inductance are enlarged.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"7 1","pages":"1080-1086"},"PeriodicalIF":0.0,"publicationDate":"2018-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82886150","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 stray inductances inside the converter circuit caused by among DC capacitors, bus bars, and power module package are one of the most critical parameters, which influence not only the over-voltage but also the switching loss. This paper proposes a quantitative design procedure for the switching losses depending the stray inductances. This paper focuses on the effects of stray inductance on both the turn-on and turn-off losses, and the quantitative analyses are explained using a stray inductance scaling method.

This allows to put the focus on the research topics themselves rather than spending a high effort on the pure implementation of the theoretical research results. The system described in this paper consists of a software environment/toolchain and a hardware platform. The hardware platform can be subdivided into a power electronics platform and a System on Chip based signal processing system.

The proposed system achieves a reduction in radiation noise by canceling the noise using multiple coils, which are placed opposite to each other. However, in IPT systems with multiple coils, a magnetic interference among the multiple coils decreases a transmission efficiency due to the occurrence of circulating current. The proposed three-phase IPT system achieves cancellation of the interference using six coils on each side. First, the IPT system with the 12 coils is proposed. Then, a canceling condition of the magnetic interference among the coils is mathematically introduced from the voltage equation on the coils. Finally, the proposed IPT system is experimentally demonstrated with the 3-kW prototype.

Among the WBG devices (SiC, GaN), SiCs (Silicon Carbide) are considered to be the most preferable choice for the medium and higher power levels due to their reliability in physical construction. The major part of the loss reduction in SiC devices come from the lower on state resistance and the reduction in the reverse recovery losses associated with the antiparallel diodes. The total estimated loss reduction can be around 70% in SiC based converters compared to the Si based ones. However, there are issues related to driving these switches at safer operating area (SOA) with reduced switching losses at higher switching frequencies (20 kHz – 100 kHz), which also leads to a significant EMI/EMC issues in comparison to Si device (Operates at 20 kHz maximum). Higher switching frequency of operation further increases the effect of stray capacitances and associated oscillation which might not be acceptable for stable system operation. This paper will present different applications of SiC based inverters, challenges associated with high switching frequency SiC driver design and the problem with commercially available drivers.","PeriodicalId":6610,"journal":{"name":"2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia)","volume":"4 1","pages":"3401-3405"},"PeriodicalIF":0.0,"publicationDate":"2018-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78669320","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}
