Energy storage systems (ESSs) must be designed by a trade-off between specific response time and energy density, because one single energy source is insufficient to supply such a high power system. Integrating ESSs with different capabilities, such as fuel-cell, battery, and supercapacitors, as a single energy source is required. In this context, a resonant multiwinding transformer-based (MTB) converter can be used to efficiently interconnect these different ESSs to the load, since the resonant converters are able to operate at a high switching frequency and hence enable high bandwidth control. However, due to the multiple resonant circuits and possible parameter deviations, the control capability might be compromised. Thus, a multiport resonant dc-dc converter embedded with variable inductors is proposed to enhance the power flow management among these different ESSs with reduced conversion stages. Further, the proposed concept can also improve the immunity to parameter deviations on the resonant by compensating the resonant frequency. Finally, simulations and experimental results of a 4-port resonant dc-dc converter embedded with variable inductors are presented to demonstrate the effectiveness of the proposed system.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127161178","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}

These split inductors prevent current shoot-through with zero deadtime operation, which lowers the distortion in the output waveforms and makes this topology ideal for fast-switching devices such as SiC or GaN. Further, decoupling between top and bottom device's output capacitance also results in lower overall switching loss and improves Electromagnetic Interference (EMI) performance. However, the split inductors experience current spikes during switching transition, which can lead to significant core loss. This paper presents a comprehensive analysis of current spikes in a split phase inverter with SPWM, characterized by the load power factor (PF). The proposed model can be used to optimize the size of split inductor. At first, the circuit of a single phase-leg with split inductors, is analyzed and a mathematical model for spike current estimation is proposed. The proposed model is verified on a SiC-based hardware prototype switching at 72 kHz. It is shown that the spike amplitude depends on the load PF as well as on the values of the split inductors and parasitic capacitances of the power semiconductors. Lastly, the proposed model is extended to the three-phase configuration.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127218375","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}

With the introduction of wide-bandgap (WBG) devices coupled with the soft-switching feature, switching frequencies can be extended beyond mega-hertz. However, the design of the magnetic components (trans-former and inductor) becomes more challenging to accommodate for high efficiency, high power density, and lower cost. This paper leverages the printed circuit board (PCB) to integrate a matrix of four transformers plus a resonant inductor in a novel five-leg magnetic core structure. The proposed design allows controllable leakage inductance for the matrix transformer within the footprint of the original matrix transformer, which offers excellent power density for the magnetics. The proposed structure is used to implement a regulated CLL resonant con-verter. The magnetic concept is demonstrated on 3kW 400V/48V CLL converter addresses for the data center applications. The converter achieves a power density of 550W/in3 and a peak efficiency of 97.3%.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127132201","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 improve the system's EMI performance, a novel four-level active gate driver (4-L AGD) with independent adjustable turn-on and turn-off gate voltages is proposed. Based on the trajectory modeling of the SiC MOSFET, $dv/dt, di/dt$, switch losses can be optimized by applying different intermediate voltage levels during turn-on and turn-off transients to improve the system EMI performance, suppress voltage and current overshoots and oscillations. Compared with the existing AGD with the fixed intermediate voltage, the proposed AGD's intermediate voltage level can be flexibly and continuously adjusted in a very wide range during both turn-on and turn-off transients. The proposed AGD working principles, trajectory modeling and the optimizations of the intermediate voltages are analyzed. Finally, simulations and experimental validations are carried out on a double pulse test platform with different intermediate voltages. The proposed AGD has the capability to fine tune $dv/dt, di/dt$ and suppress overshoots effectively according to the experimental results.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114284515","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, simulation challenges show up due to high-frequency operation and resultant computational burden. This paper attempts to leverage the advanced computing technology, which has been successfully demonstrated in power system simulation, and performs the quantitative study to demonstrate the effectiveness of simulation acceleration. First, a methodology is proposed for a comprehensive comparison in a quantitative manner, starting from commercial MATLAB/Simulink software as the benchmark along with mathematical model (numerical and analytical version), Julia implementation, and improved model using paralleling computing techniques. Second, based on the proposed methodology, a case study with the widely applied two-level voltage source converter is performed and the comparison results are summarized. The impact of switching frequency is also investigated. It is observed that the simulation speeds up by a factor of 43.8 using advanced computing technology as compared to the MATLAB/Simulink benchmark.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125725337","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}
