Additionally, it can work under over-modulation condition (i.e., arm submodule clusters may generate negative voltage during a fundamental cycle) to improve the utilization of submodules (SMs). Regarding the over-modulation issue, this paper proposes a reduced-switching-frequency modulation method, considering the different dynamics of FBSMs and HBSMs, for hybrid MMCs. Moreover, an improved wave-distributing approach which can reduce losses and make the operating time and losses of the two types of SMs more even than the conventional method is presented. Finally, the effectiveness of the proposed method is verified by an over-modulation hybrid MMC simulation model built based on PSCAD/EMTDC platform.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115135838","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}

Recovered energy can extend electric vehicle's traveling distance. This paper presents a braking control strategy for a de-excited flux switching machine which is designed to drive small electric scooters. Regenerated energy during motor braking is stored in a super capacitor. During braking period, the field winding and its driver is controlled such that the braking energy can charge the super capacitor, or the stored energy can be discharged back to the dc link. No addition inductor is required. The relationships between recovery energy, braking speed, deceleration rate, and load inertia are analyzed. The analysis considers all the losses in the motor and drive. The optimal deceleration rate for energy recovery is calculated and used for control. Experiments are performed to verify the proposed control strategy.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115428422","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 Line Regulating Converters (LRCs) consist of parallel-connected submodules based on the single-phase Dual Active Bridge (DAB) topology. The load side converters (Point of Load (POL) converters) are tightly regulated buck converters, which exhibit Constant Power Load (CPL) behavior with destabilizing effect on the MVDC bus voltage. We apply here an Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) strategy to the MVDC SPS and evaluate its performance by simulation in MATLAB Simulink. The analyzed scenarios consider large disturbances such as load step up, submodule disconnection and LRC module disconnection. Furthermore, we prove that the entire MVDC is Port-Hamiltonian and therefore the system stability is guaranteed by the IDA - PBC.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115469788","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 data transfer sharing the existing power coils is an attractive method compared to the conventional far-field communication technologies. The frequency division multiplexing (FDM) technique can achieve the data transfer without interupting the power transfer. This paper proposes a general method to construct communication channels that fit the FDM technique on inductive power transfer (IPT) topologies. According to this method, nine kinds of communication channel structures can be derived for the four basic compensation topologies. The high transfer gain of data carrier is achieved without changing the power carrier transfer path. The communication interference from the power harmonics can be effectively suppressed. The proposed communication channel is simulated and verified by experiments.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115656002","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}

Its low design and computational cost are particularly suited to the autonomous signal processing requirements for the Internet of Things. This paper describes how arbitrarily narrow bandpass filters may be designed and implemented using a chain of six Prisms. In one simulation, a design with 40 MHz sampling rate, 1 MHz central frequency and 0.1 Hz bandwidth results in an FIR filter of length 771 million samples. This filter can be evaluated in 0.39 μs per sample on a desktop computer: to achieve this update rate using a conventional non-recursive FIR calculation would require supercomputer resources.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123111325","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 proposed scheme is comparable to a variation of gate resistance of one decade without the inconvenience of the gate resistance. The approach is first validated by circuit simulation then experimentally. The advantages of such an approach are then demonstrated thanks to the comparison with a conventional passive control method.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123086136","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 order to ensure highly reliable operation of the Optiverter, this paper analyzes the wear-out failures of the Optiverter considering both 60- and 72- cells Si crystalline PV modules. The lifetime evaluation of the Optiverter also considers the impact of module degradation rates and different mission profiles into consideration. The evaluation results reveal that operating the Optiverter with a high-power PV module (i.e., 72-cell) results in a lower reliability performance compared with 60-cell PV module. This is mainly due to the higher power and thermal loadings of the power devices in the Optiverter with a 72-cell PV module. When considering the effect of module degradation, using the 72-cell PV module also lead to a higher deviation in the reliability prediction compared to the case without considering the degradation.","PeriodicalId":370319,"journal":{"name":"IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121804564","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}
