As the effect of third order harmonic is most profound in the frequency spectrum of the input current, a closed-form mathematical model correlating the third harmonic component as a function of the load power, input voltage, and the closed loop controller coefficients of the TPFC is established. Further, with an objective to curb the third harmonic component, a novel digital filter based Active Mitigation Scheme (AMS) is proposed in this study. Extensive simulation and experimental results are included in order to validate the performance of the proposed theoretical model and affirm the effectiveness of the proposed AMS scheme. The results portray an accuracy of 97% of the formulated third harmonic model, when compared with the simulation and experimental results. Moreover, implementation of AMS results in a superior power quality with 0.77% reduction in the Total Harmonic Distortion (THD) while achieving a resultant power factor of 0.998 (lag).","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115884919","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}

Nowadays, SiC MOSFET & Si devices hybrid converters have been demonstrated as a high-performance and cost-effective solution. In this paper, a SiC MOSFET & Si devices hybrid four-level ANPC converter is proposed, which requires only two SiC MOSFETs with relatively low blocking voltage in each phase. In order to solve the voltage balancing problem in this circuit, a multi-step soft-switching modulation strategy is then proposed. Implementing the proposed modulation, only SiC devices undertake hard-switching at switching frequency and Si devices are all in soft-switching mode. As a result, the proposed converter has high efficiency but significantly lower cost compared to the all-SiC-MOSFET-based converter in the same topology. The proposed topology and modulation scheme are verified by simulation and experimental results.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115956578","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 unique aspect of the method is the use of multi-interface power electronic converter for the grid and ESSs and EVs that can support a range of applications with ac / dc and dc / dc energy conversion ability in a single converter system. The key enabling technology to achieve these functionalities is Oak Ridge Converter (ORC) with polyphase coupler coil system both developed at ORNL. This new technology enables higher power density WPT systems while allowing the coils to interface from ac grid at 60 Hz frequency or dc source directly merging with 85 kHz operating frequency of switching component. The experimental results of the proposed system are presented for 20 kW output power with the system overall efficiency around 95.4% from dc source and 93% overall efficiency from ac grid achieving 9-10% current total harmonic distortion (THD) and 0.98-0.99 power factor (PF).","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130269294","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, their reliability has been a concern for the industry, primarily since these devices have been used commercially only for a few years. Hence, this paper presents a method for the remaining useful lifetime (RUL) prediction of GaN-based converter system in real-time. Considering the most critical parts of failure in the power converters are the GaN devices and the capacitors, experimental degradation data for 10 GaN devices, and 4 capacitors were extracted over several weeks of operation in a laboratory setup. The degradation data mainly includes the measurements of the drain-source resistance for the GaN devices, ESR for capacitors, and the components' temperature. A statistical approach using probability density functions (PDFs) in uniform distribution is proposed to predict the probability of survival at the system level, based on the experimental degradation data. The RUL prediction accuracy using the proposed PDFs method is high since it utilizes real qualification data. Under different operating profiles (temperature and current stress levels), the degradation data is extracted. Finally, detailed analysis and discussions are pointed out based on the experimental results.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133155140","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 2kW, 8.33kHz, high-power-density UHS-PMSM is designed for operating the AMEBA. Robust high-speed control of this motor is crucial for an accurate transmission of the signal. However, motor performance and system stability deteriorate due to parameter variation at increased temperature and frequency. To address these issues, a novel fast Anti-Disturbance Sliding Mode-based Deadbeat Model Predictive (ADSM-DMP) control is proposed for precise speed control and to minimize the effect of dynamic parameter variation. The proposed controller achieves 47.7% faster settling time, 96.7% reduction in average torque fluctuation, and 12.46% reduced total harmonic distortion (THD) in current. For experimentally validating the proposed controller, cascode GaN-FET based inverter is designed to operate in high frequency and high-temperature regions.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116983688","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}
