Multiphase parallel LLC resonant converter is necessary in low voltage and large current condition, however, there is a difficulty lying in current sharing. The small tolerance in the resonant tank may cause the larger current imbalance of the multi phases. This paper proposes a control strategy for parallel LLC resonant converter based on sigma converter regulated by PWM controller, which can solve load-sharing problem. The current sharing of each phase is achieved by balancing the output current of Buck. Moreover, LLC-DCX (DC Transformer) of each phase handles most of the energy, the high efficiency is guaranteed. A 200W two-phase parallel sigma converter is given, the simulation results show that the proposed control method can reduce the imbalance of output current significantly within the full load range, verifying the current sharing control strategy effective.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127402251","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}

Sequential model predictive control which uses two sequential cost functions to select voltage vector shows many advantages in eliminating weighting factor and improving development efficiency. However, its artificially prescribed order of cost functions and the number of selected voltage vectors greatly affect control performance. While keeping the advantages of no weighting factor tuning, this paper proposes a sequential predictive duty cycle control (SPDCC) solution for induction motor drive. The sequential cost function with additional variable parameter is designed to balance better the weighting relationship between electromagnetic torque and stator flux. To improve the effect of the single voltage vector, the duty cycle control based on torque deadbeat is applied in a symmetric manner. The simulation results show the effectiveness of the proposed method.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127253739","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 conventional spoke-PMSM (CS-PMSM) exhibits high possibility of PM demagnetization and lower maximum speed in flux weakening region due to its operation with negative d-axis current. Besides, it requires high flux-weakening current, and thus exhibits lower efficiency for operation above rated speed. These drawbacks are overcome by the developed FIS-PMSM, which is designed while considering the flux-intensifying effect. Multiple flux barriers are introduced in q-axis flux path of the designed motor, which thereby results in positive saliency difference. Hence, the developed FIS-PMSM generates maximum torque on application of flux-intensifying current. To demonstrate advantages of FIS-PMSM, the comparison is made with the CS-PMSM, wherein an increment of 14.3% in operating speed and 21% increment in PM operating flux density are obtained. The other electromagnetic performances like torque curves, inductance profiles and efficiency plots are also acquired by performing finite element based simulation.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"586 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127255513","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}

This paper compares grid-following and grid-forming control structures under fault conditions, i.e. it is focused on the transient stability.
