This testbed can be executed in PC-layer for offline simulations or can be executed in real-time on the National Instruments (NI)-CompactRIO (cRIO) platform. The discrete-time models are implemented on the Field Programmable Gate Array (FPGA), using LabVIEW, and validated against a physical hardware setup. The emulated stator and rotor currents and DC-link voltage are compared against physical measurements creating a validated platform independent from third-party models and suitable for applications in real-time. The proposed testbed is intended to be available to researchers, wind turbine manufacturers, and utility companies to perform tests using a validated platform to verify proposed control designs of DFIG wind turbines.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"8 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131702429","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}

Instead of using a conventional boost converter with large DC-link capacitors, we accomplish PFC-functionality by shaping the charging current into a sin2-shape. In addition, a novel control scheme without input-current sensing is introduced. A-priori knowledge is used to implement a feed-forward control in combination with a closed-loop output current control to maintain the target current. The use of a full-bridge/half-bridge LLC converter enables operation in a wide input-voltage range.A fully featured prototype has been built with a peak output power of 1050 W. An average output power of 400 W was measured, resulting in a power density of 1.8 kW/dm3. At 9 A charging current, a power factor of 0.96 was measured and the efficiency exceeds 93% on average with passive rectification.The impact of pulse charging has been evaluated on a 400 Wh battery which was charged with the proposed converter as well as CC-CV-charging for reference. Both charging schemes show similar battery surface temperatures.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133696089","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 zero crossing frequency of battery impedance phase can reflect the aging status of battery based on the observation from the aging data. However, the relationship between the zero crossing frequency and SOH is nonlinear. In order to model this nonlinear relationship for SOH prediction, ANN as a powerful nonlinear fitting tool or method is explored in this paper in order to characterize this relationship. The designed ANN can update its parameters based on the feedback data from the operation of the system. This feature makes the proposed method be able to adapt to the changes in the operation conditions and aging conditions of the battery, which enables better SOH prediction accuracy compared with the static SOH model methods when the operation conditions or battery conditions are different from the ones that the static SOH models are derived from. The proposed SOH estimation method also allows for fast prediction compared with the conventional capacity fading methods. This is mainly because the parameter used for SOH prediction, i.e. battery impedance phase, can be obtained within a short time during the online operation of the system. A preliminary experimental prototype is built in the laboratory to verify the proposed method.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114588531","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, the reverse LLC voltage gain is lower than unity. The DC-link voltage is then lower than the peak grid voltage so that the buck type DC-AC converters cannot be grid-tied directly, which causes the LLC reverse operation difficult in bidirectional charging applications. This paper proposed a SiC bidirectional LLC on-board charger architecture to achieve high efficiency and high power density. The first stage is an interleaved bridgeless totem pole PFC to achieve unity power factor. The second stage is a 300-kHz LLC taking advantage of wide ZVS range and magnetic integration. Thanks to extra control freedom of high DC-link voltage, the DC-DC voltage gain regulation burden is shared by the DC/AC stage taking advantage of high voltage SiC MOSFETs. An LLC reverse voltage gain compensation control by regulating DC-link voltage is proposed to enable the LLC bidirectional operation. A digital adaptive synchronous rectification driving scheme is proposed based on the LLC primary driver signals. The adaptive SR on-time is modified in every switching control cycle guaranteeing fast transient response and suitable for high frequency applications. A prototype of 6.6 kW SiC bidirectional LLC charger was built and the battery voltage from 240 V to 420 V. The power density is 44 W/in3 with 3 kW /kg and increases 22.2% over the Wolfspeed design. The charging peak efficiency is 95.3% through, and 1.3% higher than the state-of-the-art products. The peak discharging efficiency under 6.6 kW is 95.6%, and 0.6% higher than the state-of-the-art efficiency.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116990481","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}

It offers a flexibly adjustable conversion ratio for a wide-range battery voltage. The unregulated stage is modularized with resonant switched capacitor converters. All device voltage stresses are equal to the input voltage. The efficient unregulated stage processes the bulk of system power and the less efficient regulated stage processes a small amount of power. Thus, high overall efficiency can be achieved. A new index called Semiconductor Loss Index (SLI) is defined as a function of semiconductor die area to evaluate different power topologies. It is helpful to analyze the impact of each switch die area, different operated output power, switching frequency, and conversion ratio on the total device power loss. With the same total semiconductor die area, the proposed converter can achieve less than 1/3 device total power loss compared with boost converter. A 4-kW 1200V output converter prototype with 200V~400V input voltage range is developed, which combines a 6 times conversion ratio STC with a PPVR buck converter. The overall full-load efficiency of designed 4-kW converter can reach to 97.71%. Simulation, prototype and experiment results are presented to verify the validity of the proposed converter.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122178077","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}
