To achieve this, the cause of overshoot that occurs when the load decreases is analyzed, which is found to be due to the magnitude of the voltage applied to the inductor, which is the difference between the input and output voltages. The proposed switching control strategy ensures that only the output voltage is applied to the inductor. The proposed method reduces overshoot by about 55%, from 42V to 19V, and this has been verified through simulation.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129080776","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}

However, due to its asymmetric operation, the AHB converter suffers from degraded efficiency. To improve this drawback, several approaches have proposed a new secondary rectifier structure. Among various rectifier structures, the series capacitor rectifier (SCR) structure has a strong advantage such as the zero dc-offset current and balanced average current of diodes. However, it suffers from weakened energy for zero-voltage switching (ZVS) under light load conditions. In this paper, simple synchronous rectifier (SR) switch control is proposed. The strong point of the proposed converter is that it can simply integrate two different rectifier structures by replacing two diodes with two SR switches. Consequently, the proposed converter can achieve higher efficiency than previous AHB converters. The feasibility of the proposed converter is verified with a 48 V/400 W prototype converter.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130579644","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}

In conventional gate drivers, switching events are often slowed down to avoid unevenly distributed losses of parallel-connected SiC MOSFETs. Due to the reduced switching speed, wide-bandgap (WBG) semiconductor devices are not fully utilized. The presented gate driver selectively delays the individual gate signals of the parallel-connected MOSFETs to influence the switching losses. To balance the temperature of the MOSFETs during operation, a closed-loop control is designed and verified by measurements. The presented gate driver thus enables a balanced stress of parallel-connected MOSFETs and a uniform aging of the MOSFETs. Therefore, the potential of parallel-connected WBG semiconductor devices can be better utilized and a derating of the system is avoided.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116286062","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}

Three-phase grid-connected converters provide an interface between the utility grid and distributed power sources such as photovoltaic (PV), wind turbines, energy storage systems, etc. Synchronization of these converters are always achieved through Synchronous Reference Frame (SRF). Thus, impedance-based stability analysis under SRF becomes a powerful tool to assess the system stability and optimize the converter design. However, precise measurement of the system impedance can be a difficult task in practice, particularly for high-capacity converters. In this paper, a hardware-in-the-loop (HiL) platform is proposed for measurement of the SRF impedance. Consequently, the impedance of an Active Front End (AFE) converter is measured and compared with the analytical small-signal model. The results show that measurement with the proposed HiL setup provides a powerful and accurate solution for impedance measurement that precludes the need for complete hardware testing.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128018552","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}

To reduce the inductor currents in the FBC converter, the interleaved boost converters (IBC) are used instead of single boost converters so that the four-phase floating interleaved boost converter (4P-FBC) is formed. However, it is well known that the IBC suffers a significant problem with the unbalanced inductor currents issue, leading to high input current ripple. This paper proposed a floating double series-capacitor boost (FSCB) converter to solve the problem. Moreover, the voltage gain is improved by more than double, and the input current ripple can be minimized. As a result, the proposed converter is suitable for new energy sources, such as fuel-cell and photovoltaic. A 1.6 kW prototype was built and tested to verify the performance of the proposed converter.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128027988","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 employs the current droop control as an autonomous distributed control to achieve the voltage balance of each cell and prevent overmodulation without communication among each cell.
