Compared to the capacitive ones, the inductive couplings introduced by layout traces reveal a contradictory effect under the low-impedance gate loop design, thus limiting the suppression effectiveness of active clamping. To alleviate this issue and suppress the inductive crosstalk from the origin, this paper proposes a cancellation layout structure to reduce the inductive power-gate couplings. At first, the fully-coupled inductance model for MCPMs is developed after analyzing the crosstalk mechanism considering inductive coupling. Then, based on the model, a coupling cancellation structure is designed by introducing the gate trace with the negative mutual inductance. As a result, the cancellation structure is compact, flexible, and easy to implement. Finally, simulations and experiments are conducted to verify the effectiveness of the proposed technique.","PeriodicalId":268264,"journal":{"name":"2021 IEEE 1st International Power Electronics and Application Symposium (PEAS)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125123979","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}

Taking low electromagnetic force fluctuation as optimization objective, the sensitivity of key dimension parameters is stratified based on sensitivity analysis. According to the parameter sensitivity level, the multi-objective optimization analysis based on genetic algorithm and single parameter scanning method are combined to determine the optimal parameters of the motor.

The LLC DCX converter can be very high efficiency and can work in a very high switching frequency which means high power density, but it can not regulate the output voltage, so the LLC DCX converter is an unregulated converter [1]. The four switch Buck Boost converter can regulate output voltage, step up and step down, but its efficiency and power density is low because of its hard-switching feature [2]. The four switch Buck Boost converter can cascade with the LLC DCX converter to make up a two stages architecture converter for the 48V-to-1V application [3]. As the cascade structure, the regulated converter rated power is 100% which deteriorates the efficiency and power density. The unregulated converter rated power ratio of the proposal converter can be increased to at least 73% so the new topology has an efficiency close to LLC DCX’s.","PeriodicalId":268264,"journal":{"name":"2021 IEEE 1st International Power Electronics and Application Symposium (PEAS)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130317711","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 multi-time scale model can perform electromechanical electromagnetic transient hybrid simulation, which can be applied to the research of power systems with high renewable energy penetration. The power electronic converter models are built on the Typhoon platform with FPGA as the core computing unit while the power grid is implemented in the spaceR platform. Due to the intrinsic discrete nature of the real time simulation system, a new type of delay is introduced in the simulation model. When studying the stability of grid connected inverter in weak grid, the delay will bring an impact that cannot be ignored on the simulation platform. Therefore, based on the classical impedance-based stability criterion, we analyze the influence of this new delay type on the system in this paper with the support from the real time simulation verification.","PeriodicalId":268264,"journal":{"name":"2021 IEEE 1st International Power Electronics and Application Symposium (PEAS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129589138","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}

Thus, this paper proposes a novel Hbridge hybrid FCL to realize a tradeoff of comprehensive performance. The current commutation branch in the FCL can bidirectionally limit the rate-of-rise of the fault current during the current transfer stage. The working principle and the electrical stress analysis are presented and the impact of the hybrid FCL on the transient energy transfer is analyzed. These approaches are validated by simulations of a ± 500 kV bipolar HVDC grid in PSCAD/EMTDC.
