The operating principle of the proposed interleaving three-level bidirectional DC/DC converter as well as the influence of the duty ratio on the operating state are analyzed in this paper to establish a state-space averaging model. Using the double loop control did not reduce the dynamic response speed of the converter, and the current loop suppresses the interphase circulation.

Each of its three phase modules is operated independently and consists of a boost-buck converter, allowing to directly convert an AC voltage into an arbitrary DC voltage by only modulating one of the two converter stages at a time, where the AC voltages are applied against a reference point common to all phases. Hence, single-stage high-frequency energy conversion is enabled, resulting in a highly compact and highly efficient converter system realization. In a first step, the basic structure of the phase-modular converter (PMC) is derived from the well known cascaded arrangement of a three-phase boost-type rectifier and a subsequent DC/DC buck converter, followed by a discussion of its operating principle and characteristic waveforms. Furthermore, the corresponding DC output voltage control scheme is presented which allows a seamless transition between buck and boost operation in each phase module. Finally, the phase-modular converter and the conventional two-stage system are compared by means of simple indices as well as a two-dimensional Pareto optimization concerning efficiency $eta$and power density $ rho $.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125122632","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}

Estimating the SOC of lithium battery based on the traditional unscented Kalman filter (UKF) algorithm has better estimation precision, but the application condition of the algorithm is that the statistical properties of the state process noises and measurement noises are known clearly. This paper proposed the dual adaptive unscented Kalman filter (DAUKF) algorithm which is combining the traditional Kalman filter (KF) algorithm and the adaptive unscented Kalman filter (AUKF) algorithm. Firstly, a second-order Resistor-Capacitor (RC) model of lithium battery is established, the KF algorithm is used to identify the model parameters online. Secondly, the AUKF algorithm based on Unscented Transformation (UT) is utilized to estimate the SOC. And then the implementation steps of the DAUKF algorithm are introduced in detail. The experimental results indicate that the DAUKF can estimate the SOC with error less than 1.0% under the conditions of the constant exile electric, the constant current charge and discharge and the urban dynamometer driving schedule (UDDS) cycle. Compared with the dual unscented Kalman filter (DUKF), the DAUKF has stronger estimation precision and better adaptive tracking ability.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125638884","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 control the harmonic current of FPMSM better, the dual d-q current control of FPMSM is necessary. So the dual vector space SVPWM(DVSVPWM) is particularly important. In order to improve the dual d-q current control of FPMSM, this paper proposes a novel dual plane space voltage vector modulation method based on space six vector(SV-DVSVPWM). The method of PWM waveform centralization can effectively solve the problem that the asymmetry of the PWM waveform. And a harmonic compensation method is proposed furthermore, which can completely eliminate the harmonic voltage in the harmonic subspace. The SV-DVSVPWM with compensation is used in the dual d-q current control of FPMSM. Finally, the simulation verified the correctness of the proposed modulation method and the validity of harmonic compensation. The experiment with dual d-q current control of FPMSM based on SV-DVSVPWM is verified, and an excellent current control effect is achieved.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131186525","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}
