Finite control set model predictive control (FCS-MPC) has strong robustness and fast dynamic response, so it is widely used in the control system of grid-connected inverter. However, the traditional FCS-MPC bears with irregular switching state, which will reduce the current tracking accuracy, accidentally produce high current ripple and electromagnetic noise. Aiming at the above shortcomings, an efficient and fixed operation frequency model predictive based on the discrete space vector modulation (MPC-DSVM) is presented in this paper. Firstly, the mathematical model and voltage vector of NPC-type converter are given according to the principle of deadbeat control. By applying the virtual vectors which are linear synthetized with the real vectors, the MPC-DSVM method can output more voltage vectors with fixed switching frequency. The results obtained show that the current tracking accuracy is improved, the current distortion and imbalance of neutral point potential are reduced.","PeriodicalId":268264,"journal":{"name":"2021 IEEE 1st International Power Electronics and Application Symposium (PEAS)","volume":"51 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":"128808908","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}

A double-layered (DOL) energy management strategy which is composed of fuzzy control layer for lithium battery and variable power reference filter layer for fuel cell system is proposed in this paper. The first layer is the fuzzy control layer which adds the extra input power reference of fuel cell, and it is related to efficiency of fuel cell system and state of charge of lithium battery. Second layer possesses a variable parameter which can keep the power reference of fuel cell close to the highest efficiency point and it has a good effect on the health and efficiency of fuel cell. By combining two layers, both SOC of lithium battery and efficiency of fuel cell system are regarded as the optimization objectives. For verifying proposed EMS, it is compared with finite state machine (FSM) energy management strategy and the simulation results shows that proposed EMS outdoes FSM EMS. In 50% initial SOC condition, average efficiency of fuel cell system and equivalent hydrogen consumption of the proposed EMS are 2.13% higher and 1.7g lower than FSM respectively, and they are 1.84% higher and 1.5g lower than FSM in 80% initial SOC condition. In addition, the proposed EMS is a real-time approach without demand of much calculation resource.","PeriodicalId":268264,"journal":{"name":"2021 IEEE 1st International Power Electronics and Application Symposium (PEAS)","volume":"21 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":"125564823","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}

Maintaining the negative inductor current within a certain range through variable frequency control, which can make the converter have high efficiency in a large load range. The application of gallium nitride (GaN) devices can further increase the switching frequency of the converter, which is very critical in the application of CRM mode. Parallel converters must solve the problem of uneven current distribution. This paper proposes a new digital current sharing control strategy without adding auxiliary circuits. On the one hand, this control strategy achieves accurate current sharing among different modules through reasonable current sharing control. On the other hand, it uses formula calculations to change the switching frequency in real time to maintain the CRM mode to improve efficiency.

To achieve an embedded voltage-boost capability, this paper proposes a novel seven-level inverter based on the H-bridge (HB) inverter, whose two half-bridge legs are cascaded with a three-level T-type (3LTT) inverter, respectively. The proposed inverter is supplied by a single dc source in series with an inductor. The inductor is charged by the dc source when shooting through the HB switches. Voltage boosting is therefore embedded into the proposed inverter without extra switches. Auxiliary circuits for balancing the voltages of capacitors are not required either, since each capacitor can be charged by the inductive dc-link with the same step-up average voltage. The carrier-based phase-shift pulse-width modulation (PWM) scheme is applied to the HB inverter to produce two inductive-charge states within a switching period. The operating frequency of the inductor is thus doubled, reducing the high-frequency input current ripple. Operating principles and theoretical analysis of the proposed inverter are given. Simulation and experimental results agree well with each other, verifying the feasibility of the proposed inverter in achieving a boosted seven-level output voltage.","PeriodicalId":268264,"journal":{"name":"2021 IEEE 1st International Power Electronics and Application Symposium (PEAS)","volume":"10 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":"132613132","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}
