Recently, the monolithic Schottky barrier diode integrated SiC MOSFET (SiC JMOS) has been developed to achieve a higher utilization rate of the SiC chip area. However, the reliability of barrier diode integrated SiC MOSFET under surge current stress is a critical requirement that has to be taken into account for in power applications. In this paper, a comparative surge current capability evaluation between a SiC JMOS, SiC DMOS, and SiC Schottky barrier diode was presented. The experiment results show that the surge current capability of the SiC JMOS is weaker than that of the SiC DMOS but is better than the SiC SBD under the same current density condition. The gate breakdown is the critical factor limiting the reliability of the SiC JMOS and SiC DMOS under surge current stress. SiC JMOS show no significant degradation after up to 10k cycles repetitive surge current stress at 80% of surge current limit, while the SiC SBD is more likely to degenerate under repetitive surge current stress.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125420626","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}

Steady-state terminal voltage and current information of the GCI part which are necessary in conventional dq impedance modelling methods are calculated based on grid parameters, i.e., grid voltage and grid impedance, and current references of current-controlled GCI or power references of power-controlled GCI. In addition, effects of dynamics of grid voltage and phase-locked loop (PLL) on dq impedance characteristics of grid part are also investigated, which enables the modified dq impedance model of grid part to relate with that of GCI part. The modified dq impedance model of the GCI part which takes the effects of grid voltage and grid impedance into account need not know steady-state terminal voltage and current information. In addition, the modified dq impedance model of grid part may provide accurate stability analysis during grid voltage changes. The insight of instability mechanism of the GCI-grid coupling system may be facilitated using the modified dq impedance models.

Triangular conduction-mode (TCM) generate a reverse current which discharges a junction capacitance before a MOSFET turns on. Such a method has been extended to three-phase applications by operating the other two phase into two different conduction-modes; discontinuous conduction mode (DCM) and clamp-mode similar to a discontinuous PWM (DPWM) scheme [1]–[4]. However, the presence of a three-phase coupling and transitions of the conduction-modes along the line-cycle arise complexity in the modeling and control. In this paper, a modeling approach is presented for three-phase inverters utilizing three different conduction-modes for ZVS operation. It is revealed that the modeling and analysis for an equivalent single-phase TCM and DCM inverter can be directly extended to the three-phase case. The impact of the DCM phase can simply be calculated and compensated. Control schemes for single-phase inverters can be extended to the three-phase counterparts. The proposed modeling approach is verified by SIMPLIS simulation and an experiment with the prototype three-level three-phase TCM inverter.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122306246","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}

Two-stage converter topology is considered, where the Active Front End (AFE) is directly connected to the 4.16kV MV grid. The MVDC output of the AFE is processed by the isolated DC-DC converter to achieve the output voltage that is compatible with the EV battery. Thanks to the reconfiguration capability, the proposed XFC can charge both 400V and 800V EVs without any significant performance degradation. The data collected through experimental characterization of the 10kV SiC MOSFETs is used for simulating the complete converter of MV-XFC and performing loss analysis through MV SiC modeling in PLECs software. Analytical transformer losses and multiobjective design optimization are obtained using MATLAB. Based on the outcome of the multiobjective design optimization, the converter design parameters are selected and the trade-off between the loss and volume of the proposed design has been evaluated.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115872051","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 method uses MPC to ensure compliance with cell-level operational limits and has the potential to extend lifetime by mitigating certain mechanisms of cell degradation leading to capacity fade. A five-state electrothermal model is developed, characterized and validated. Implementation employs an extended nonlinear Kalman filter for state estimation and MPC for controlling charge/discharge current. The complete method is experimentally validated using a 26650 cylindrical format lithium-iron phosphate (LFP) cell. The new method: (i) develops a fully coupled electro-thermal model of cell dynamics; (ii) incorporates a dynamic hysteresis model to improve accuracy; (iii) employs a nonlinear Kalman filter for accurate state estimation to inform the MPC algorithm; and (iv) utilizes a modified form of MPC which correctly models direct feed-through behavior to characterize ohmic resistance.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121053542","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}
