Regarding the PEBB, 1) isolated gate drive, 2) natural convection cooling and 3) voltage clamping circuit are introduced. There are three major contributions of this paper. First, the PEBB concept is proposed for MVDC SSCB design for the first time. Second, a novel hybrid MOV based voltage clamping circuit is proposed to increase PEBB voltage rating thence enhancing SSCB efficiency. Third, a PEBB parallel packaging method is proposed based on economic analysis of compromise between efficiency enhancement and cost. A symmetrical busbar layout is proposed to ensure parallel switches consistency. A 1.33kV/40A PEBB prototype is successfully implemented, which is experimentally validated by 40A/1hour continuous conduction test and 1.33kV/200A fault interruption test. A 1.33kV/400A power disk prototype is then implemented based on 10 paralleled PEBBs and symmetrical busbar connections. A 400A/1hour continuous dc conduction test is conducted to verify its state-of-the-art 99.98% steady state efficiency, which paves the way for the next generation of high efficiency ultrafast solid-state breakers for MVDC systems.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125697187","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 inversion stage operates in buck or buck-boost mode depending on the polarity of the output voltage reference and produces a sinusoidal output voltage. Owing to the dual-mode nature of the inversion stage, output voltage regulation with standard feedback control results in a large dc-offset and poor total harmonic distortion (THD), which is unacceptable for practical applications. To substantially improve the output voltage dc-offset and THD, a dynamic cancellation control strategy is proposed for the buck-boost mode of the dual-mode inversion stage. An analytical model capturing the dynamics of the inversion stage with dynamic cancellation control strategy is also presented to facilitate the controller design. A 1-kVA GaN-based prototype of online UPS is designed, built, and tested, and the output voltage THD is experimentally measured across a wide output voltage range. Standard feedback control strategy results in a 10% output voltage THD whereas the dynamic cancellation control strategy offers a significant improvement of 68% and results in a 3.2% output voltage THD.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127943493","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}

Traditionally, the grid-tie inverter needs the voltage measured from points of common couplings (PCC) to generate the phase angle via PLL for inverter pulse-width-modulation (PWM) signals. The startup procedure is slow and inrush current occurs if the initial PWM does not match the unknown grid voltage well. This paper proposes a startup method that only uses measured inverter ac currents to generate the initial PWM by controlling the current to zero. The generated PWM pattern can be used to reproduce the real grid voltage regardless of the grid impedance. The zero-crossing points of the grid voltage are detected and then used for grid synchronization. The proposed startup procedure only needs a few cycles (16.67 ms/cycle) to reliably synchronize the inverter to the grid without any inrush current. Simulation and experimental results are presented to verify the effectiveness of this control strategy.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121727480","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}

By calculating the power loss of the proposed digital model, the temperature of self-heating devices in the digital model, such as MOSFETs, diodes and capacitors, can be obtained, so that the values of the temperature-dependent parameters in these devices can be updated, and hence more accurate results can be guaranteed.

Modern technologies with steep, sustained learning rates, e.g., solar and batteries, are capable of disrupting this trend and making energy available equitably across the population, especially if solar and storage are combined to create a dispatchable resource. Nonetheless, a cost-effective and scalable solution that integrates solar, storage, and output ac power remains the key roadblock toward distributed energy access. In this paper, a single single-stage, isolated, bi-directional micro-inverter design with reduced switch and sensor count, which interfaces with the battery, PV, and grid, is presented. It excludes large DC-link capacitors, which are commonly seen among prevailing PV converter options, and retains efficiency benefits from its design and operation. With a power rating of 1-kW, this converter can be stacked easily to scale up the total system power rating due to its current-source inverter nature. Throughout this paper, the operating principle, design, and control of the proposed micro-inverter are presented. Lastly, A 1-kVA/480-Vac hardware prototype is built to demonstrate the proposed microinverter.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131712509","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}
