The converter topology utilizes a diode-capacitor ladder network to facilitate a number of inherently-balanced voltages, which resolves the predominant constraint of MLIs having several separate dc sources. Furthermore, zero-voltage-switching (ZVS) is achieved for the solitary high-frequency switch, which mitigates the switching losses. High-frequency operation of the switch facilitates the reduced components size resulting in less cost and weight of the converter. An experimental set up for closed-loop control of the hardware prototype of the proposed converter has been developed. The performance of the grid-connected MLI is evaluated in various real-time conditions and the experimental results are presented.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"37 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":"132574780","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}

Firstly, The operation principles for the proposed SEPIC PFC with ZVS turn-on capability have been researched. Then, an E-I-E magnetic geometry has been applied to integrate all three inductors of the proposed bridgeless Single-SEPIC PFC (two input inductors and one output side inductor) into one magnetic core. The analysis of the magnetic reluctance model of the E-I-E core and the design procedure of the integrated inductor is introduced. The integrated inductors reduce the total ferrite volume and make the converter more compact.

In the multiport converter with load imbalance, a balanced three-phase current is achieved thanks to power distribution control. However, the multiport converter has a limitation on the amount of load imbalance that can be compensated. This paper derives the theoretical limitation of the compensation capabilities using the proposed balance control for the load imbalance. The proposed control method is demonstrated by simulation, showing that balanced three-phase grid current is obtained in spite of the load imbalance and that the DC link voltage error is limited to 1.4%. In addition, simulation and experimental results clarify that the proposed controller has larger compensation capability for the load imbalance compared to the conventional control strategy.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"7 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":"133771028","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}

Recently, it has been increasingly widely adopted to the control of renewable generations. To conquer the shortcomings of the large variable-ripple problems, caused by the one-voltage-vector-per-interval principle of the classical predictive methods, non-optimal multi-vector based solutions have been presented and achieved reduced control variable ripples. In this paper, we analyze the problem of the existing multi-vector based predictive control technique, and thereafter propose a new Lagrange Multipliers based predictive power control scheme with globally optimal vector design process. The proposal has been applied to a two-level grid-tied power converter, demonstrating considerably enhanced steady-state control performances in comparison with a recently reported multi-vector based predictive control technique.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"27 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":"134508523","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 MLI has many switches involved during power conditioning, which increases the possibility of fault event occurrence. The most common reliability problem in MLIs are short circuit and open-switch fault in H-bridges during the operation. A quick and precise fault detection-isolation strategy improves the system reliability and also avoids the shutdown and mal operation of the load connected. The proposed algorithm uses the root mean square values of the H-bridge voltages as the diagnostic variable at the time of fault. The fault detection algorithm is simple and can detect the fault location accurately. In addition, the proposed algorithm is able to provide rated balanced output voltage during fault without adding any additional components within one cycle. The performance of the proposed algorithm and closed loop voltage control has been verified in MATLAB/Simulink environment for a three-phase seven level cascaded H-bridge multilevel inverter.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"39 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":"134140562","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}

Saturation and inrush current are the important issues of DVR with series transformer, which may seriously affects the normal operation of the transformer and cause damage to the equipment or trigger over-current protection. To prevent transformer saturation and inrush current, a mitigation strategy of transformer saturation in DVR based on flux linkage feedback control is proposed in this paper. This method takes the flux linkage as a system state variable, and includes flux linkage loop in the control system to limit the DC flux linkage without affecting the steady-state compensation performance of DVR. The flux feedback control method is verified by simulation, and then a 0.5 kVA single-phase DVR prototype is built to validate the proposed strategy.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"68 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":"133364329","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}

Based on the half-bridge sub-module topology, this paper proposes a four-capacitor combined half-bridge sub-module (FCC-HBSM). This FCC-HBSM can not only effectively clear the DC fault current, but also self-balance the capacitor voltage after the fault. And, compared with other improved topologies, it has higher economic benefits. The single-ended MMC-HVDC is simulated by MATLAB/Simulink.
