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}

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}

For the GaN high-electron-mobility transistor (HEMT), a device without avalanche capability, its surge-energy and overvoltage ruggedness are both determined by its transient breakdown voltage (BV), which was recently found to be dynamic (i.e., time- and frequency-dependent). However, the switching frequency ($F_{text{SW}}$) in previous overvoltage studies is only a few kilohertz. This work, for the first time, developed a testbed for high-voltage GaN HEMTs enabling continuous overvoltage switching with a Fsw up to 1 MHz. Two types of 600/650-V commercial p-gate GaN HEMTs were tested under 1 MHz overvoltage switching. Both of them showed good ruggedness. The gate injection transistor showed a nearly $F_{text{SW}}$-independent dynamic BV, while the Schottky-type p-gate GaN HEMT showed a decreasing dynamic BV at higher $F_{text{SW}}$, e.g., 270-V lower when Fsw increases from 2 kHz to 1 MHz. These behaviors were explained by the buffer trapping/de-trapping in two types of GaN HEMTs and were validated via TCAD simulation. This work unveils the true overvoltage margin of GaN HEMTs in high-frequency converters.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"82 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":"121494680","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}
