However, the mismatch of the DC link voltages between the charging stations and small scale EVs may increase the difficulty of design and control of the charging facilities. Along with the growing penetration of renewable energy, vehicle-to-buildings (V2B) and vehicle-to-grid (V2G) interfaces, requiring bidirectional power flow would be the essential features of future EV wireless charging systems. In order to tackle this issue, this paper suggests a high-frequency step-up inverter based on series-parallel conversion of switched-capacitor with the associated staircase modulation and power flow control for WPT applications. Corresponding to the system parameters of a typical electric microcars, the operating principle and the power flow control of the proposed inverter are verified by simulation. The battery power as well as the primary and secondary AC waveforms of the simulation model are presented.","PeriodicalId":223569,"journal":{"name":"2017 7th International Conference on Power Electronics Systems and Applications - Smart Mobility, Power Transfer & Security (PESA)","volume":"32 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":"133678846","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 this paper, the electrical characteristic of a HD-GIT-based GaN power transistor is investigated with experimental study. Based on the gate I-V relationship, the design of the gate driver circuit is discussed. The gate driving losses as well as the switching waveforms of the HD-GIT under hard-switching operations are analyzed. Besides speeding up the switching operation, the reduction in the gate voltage and gate charge saves the gate driving power. These features substantially increase the maximum operating frequency of the HD-GIT-based power converter. The current collapse free operation allows the device working at a wide range of voltage and duty cycle without notable degradation of the dynamic on-state resistance.","PeriodicalId":223569,"journal":{"name":"2017 7th International Conference on Power Electronics Systems and Applications - Smart Mobility, Power Transfer & Security (PESA)","volume":"102 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":"130109151","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}

Fuzzy logic control (FLC) and backward propagation neural network (BPNN) control are investigated in this paper to realize position control for a linear switched reluctance motor (LSRM) against its nonlinear characteristics. Principles for FLC and BPNN control are introduced elaborately. Simulation results via BPNN show that dynamic position errors for the LSRM can be limited to 0.1 mm. Experimental results on FLC suggest that point-to-point position tracking for the motor can achieve 0.01 mm, constraining dynamic position error in 0.1 mm. By experiments, FLC for the LSRM performs better than traditional proportional-integral-derivative (PID) control, proving the effectiveness of the alleviation of the nonlinearity for the LSRM.","PeriodicalId":223569,"journal":{"name":"2017 7th International Conference on Power Electronics Systems and Applications - Smart Mobility, Power Transfer & Security (PESA)","volume":"36 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":"125402661","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}

However, machine technologies based on conventional materials are reaching to a limit. Moreover, airframe design has been predominantly built around the podded configuration of the jet engine, which compromises aerodynamic efficiency and prevents radical new design. On the top of these, the rapidly growing aviation industry also faces stringent environmental standards and economic challenges. Thus, technological breakthroughs and paradigm shifts are urgently required. A novel low inductance flux-enhancing motor is proposed for a distributed electric propulsion system for a 200-ton hydrogen fueled aircraft. A multi-domain component oriented model of the aircraft is then built to provide system performance prediction of the proposed superconducting propulsion system. Extensive simulation results show the motor outputs and the power requirements over a one hour flight, and insights into this mode of future propulsion.","PeriodicalId":223569,"journal":{"name":"2017 7th International Conference on Power Electronics Systems and Applications - Smart Mobility, Power Transfer & Security (PESA)","volume":"67 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":"131151351","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}
