Moreover, the efficiency characteristics are compared for using the SJ-MOSFET and IGBT in the boost converter. The experimental results revealed that SJ-MOSFET improves the efficiency by 0.3 percentage point more than the IGBT.

To solve this problem, electromagnetic levitation technologies have been studied. However, when a flexible thin steel plate with a thickness of less than 0.3 mm is to be levitated, levitation control becomes difficult because the thin plate's flexure increased. We propose a levitation of an ultrathin steel plate that bent to an extent that does not induce plastic deformation. It has been confirmed that vibrations are suppressed and levitation performance improved. In this study, in order to examine the levitation stability and to compare the levitation performance, bending levitation experiments were carried out on the basis of the optimal control and sliding mode control theory using thin steel plate with a thickness of 0.27 mm.","PeriodicalId":393430,"journal":{"name":"2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126346160","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}

A novel modulation strategy is proposed for the multilevel converter with the aim of minimizing switching losses.

The mitigation strategy proposed in this paper is to couple the Y point of the LCL filter capacitors to the DC bus mid-point to connect a virtual neutral to the DC bus, which significantly reduces the high frequency common mode voltages on the bus. However, additional common mode inductances and capacitances are required for this filter, to limit high frequency circulating currents and define the EMI filter breakpoint. Also, the converter current regulator must be split into differential and common mode sections, to eliminate phase coupling between the phase leg active damping current regulators, and to support damping of the common mode EMI filter resonance. The concept is verified by simulations and experimental results.","PeriodicalId":393430,"journal":{"name":"2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127926129","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 renewable energy integration filed, some information of unbalanced and distorted grid voltages, such as frequency and phase angle of fundamental wave, should be exactly and quickly detected for reliable operation. Due to the unfavorable transient response and very poor phase angle tracking of PLL based on the positive and negative sequence components decomposition with a quarter cycle delayed α variable and β variable in a stationary α-β reference frame under distorted grid conditions, a fast and exact PLL method by matrix operation of α variable and β variable of grid voltage is proposed. This process is achieved by transforming the positive, negative and low-order harmonics into multiple synchronous reference frames, and then by a matrix operation, the frequency and phase information are extracted. Thus the positive and negative sequences are separated after 5 sampling periods. The paper presents a detailed description and derivation of the proposed PLL method. Simulations and experimental results based on digital signal processor chip TMS320F2812 verify and validate the excellent performance of the new PLL method.","PeriodicalId":393430,"journal":{"name":"2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115764965","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 control approach is model predictive control where a constrained optimal control problem is solved to minimize the deviation of the torque from its reference. The dynamic model of the converters and drive is nonlinear and considers both the rectifier and inverter firing angles as control input. Controlling both firing angles simultaneously, as opposed to in a cascaded manner, implies improved potential for dynamic performance and disturbance rejection. In particular, the controller handles voltage dips on the line better than a conventional PI controller. The nonlinear MPC solution is implemented through on-line optimization. The optimization algorithm has been implemented on an embedded system and has been shown to execute sufficiently fast for the targeted control frequency.","PeriodicalId":393430,"journal":{"name":"2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)","volume":"3 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113932098","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}
