Recently, medium-voltage electric springs (ESs) are proposed to regulate the grid voltage by injecting reactive power into the distribution network that has a much lower X/R ratio (about 1) than that of the transmission network. The reactive-power-based voltage compensation performance would be adversely affected by this low X/R ratio. To address this issue, this paper presents an improved droop voltage control method for a multilevel converter (MLC)-based ES connected at the distribution voltage level. The control method would provide both active and reactive power compensation according to the grid voltage. It does not require any communication and huge modification of the original ES control loop. Therefore, it can be installed in all electric springs used at distributed level to enhance both the dynamic and steady-state compensation performance in the ac grid.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115573317","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 ANPC topology is widely used as an interface for efficient power conversion in medium-high power applications. Direct MPC allows fast and decoupled control of state-variables through a user defined cost function. However, the state-variable predictions require iteration of 27 switching vectors which increases the computational burden, making the deployment of the controller infeasible to low-cost mass-marketed DSPs. The method presented in this study restricts the number of switching states being checked through a limitation criteria. The criteria reduces the number of states being checked from 27 to just 7 at maximum, making the computational burden identical to that of a six switch 2L-VSC. The presented approach is verified by deploying the controller on a TMS320F28379D DSP and the plant on PLECS RTBox 3. In addition, the presented method is compared against an existing state-of-the-art state vector limitation technique. The results show an improvement in grid current THD throughout the power range at the expense of marginal increase in switching frequency of the converter.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115051285","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}

Compared to similarly-rated GaN HEMT and SiC MOSFET, the GaN Fin-JFET has smaller specific on-resistance, die size, and output capacitance ($C_{text{oss}}$). To exploit these merits in switching applications, an RC interface gate driver was selected with the driving strategy optimized by switching transient analysis. In the GaN Fin-JFET, the gate-to-drain capacitance ($C_{text{GD}}$) dominates $C_{text{oss}}$. Accordingly, the positive gate driver input voltage ($V_{G}^{+}$) was found to be critical to enable a fast gate charging for the Fin-JFET. Increasing $V_{G}^{+}$ from 8 V to 12 V allowed for a considerable reduction in the fall time and turn-on energy ($E_{text{ON}}$). Compared to similarly-rated GaN HEMTs and SiC MOSFETs, the vertical GaN Fin-JFET shows smaller turn-off energy ($E_{text{OFF}}$) and similar $E_{text{ON}}$, suggesting its good promise for soft switching applications. Finally, a zero-voltage switching converter based on the GaN Fin-JFET half bridge was demonstrated with a switching frequency up to 1 MHz, in which the Fin-JFET's $E_{text{OFF}}$ was extracted to be 1.7 µJunder the 400 V/6 A switching condition.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116953212","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 SSCB employs a capacitor-capacitor pair topology in a Π structure, called II-type SSCB. The capacitor-capacitor pair structure helps to achieve a reliable and fast re-closing and re-breaking process. The presented topology mostly benefits from its simplicity. It removes the voltage on passive components during the SSCB OFF-state, which enhances reliability. The II-type SSCB needs no charge/discharge circuits, and it solely depends on the dc system itself. In addition, the introduced SSCB facilities using high-power rating thyristors in the main and auxiliary branches, making it one of the best solutions for medium-voltage section. Two modified topologies are also presented to extend the applications of II-type SSCB in practice. To verify the effectiveness of the proposed topology, experiments of 500 V/50 A prototype are conducted. The results show the reaction time interval of 42 μs under load current interruption, where the peak voltage on the main and auxiliary thyristors reaches 581 V and 500 V, respectively.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117288907","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}

Both DC and switching characterizations on the wafer and packaged levels validated the predicted simulation results reported last year at APEC 2022 [1]. Packaged devices showed bidirectional operation and symmetrical performance in both directions. The breakdown voltage, on-state voltage, and current gain (ß) were measured to be 1280 V, 0.6-0.8 V, and 4, respectively [2]. Double Pulse Testing (DPT) showed significant improvement over the comparative devices in the market. We obtained ultra-low conduction and switching power losses in switching modes of operation, showing the promise of utilizing B- TRAN™ in many power electronics applications such as Electric Vehicle (EV) traction inverters, EV Off-Board Chargers, Solid-State Circuit Breakers (SSCB), Bidirectional Power Converters, Battery Disconnect Switches, IGBT Common- Emitter applications, and Matrix Converters. At 800V/14A testing, the emitter-emitter on state voltage drop is 0.6V; under the same condition, the two best common-emitter IGBT bidirectional switches [3], [4] are shown to be 2.65V.

However, they are rarely investigated together and mitigated through a control strategy at the same time. In this paper, phase voltages at the point of common coupling (PCC) and inverter output currents during the fault are firstly calculated based on the sequence network of the system. Subsequently, to ride through the fault, the hybrid mitigation strategy based on the virtual negative-sequence and positive-sequence impedance is proposed. The virtual negative-sequence impedance, realized through current feedback control, can not only reduce the overvoltage at healthy phases slightly and equalize them but also reduce inverter fault currents significantly. Besides, its weak overvoltage and strong overcurrent limiting abilities are also analyzed with varying grid short-circuit ratios and fault impedances. To limit the overvoltage, the virtual positive-sequence impedance can be increased during the fault in each control time step until the maximum phase voltage at the PCC is lower than the fault ride-through requirement. Consequently, the proposed mitigation strategy is verified by real-time simulations.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123718881","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}
