In existing topologies, the PFC stage and the primary side resonant switch network are merged into a single switch network giving rise to 25% fewer devices. Moreover, the switches in these topologies are soft switched that facilitates high switching frequency. Hence, low volume magnetic components and capacitors can be used to achieve higher power density. However, it is an unipolar voltage-fed resonant topology and also, the power transfer is unidirectional, restricting the power flow only from AC to DC side. This paper proposes a novel isolated bidirectional bipolar voltage-fed AC to DC converter which has all the aforementioned advantages. In addition, it addresses their shortcomings by generating a bipolar voltage across the resonant tanks and realizing bidirectional power flow. A modulation and control technique is proposed for generating switching pulses for DC link voltage control and bidirectional power transfer. These are demonstrated through simulations and experiments, where 1.35 kW power is transferred at 130 kHz switching frequency, 150V (L-L) AC input voltage and 200V output DC voltage.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"11 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":"133346702","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 converter is based on the phase-shifted full-bridge topology with series connected two transformers. In this topology, the transformer is not operated only as a transformer but also operated as an inductor. Therefore, output inductor is not necessary, which contributes to achieve better conversion efficiency and power density. To handle a high output current with low output voltage such as 3.3kW and realize down-sizing and high conversion efficiency, a planar type transformer using Liqualloy™ core is adapted. Since it has a high saturation flux density which is about two times larger than a typical Mn-Zn ferrite core, it does not need to open a gap in core to increase a saturation flux density which could be more suitable especially in this topology taking a high flux density due to its inductor operation. The proposed converter has the maximum output current of 244A, output voltage of 13.5V, maximum output power is 3.3kW with the switching frequency of 125kHz. In the experimental results, the peak efficiency is 96.8%, and the full load efficiency is reached at 93.7% respectively.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"95 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":"133688596","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 addition, for SiC based DC SST applying phase-shift modulation, a peak-potential state is generated between the adjacent primary and secondary winding conductors for the duration of phase shift. This magnified stress on insulation system gives rise to premature inception of partial discharges leading to sooner than predicted MF transformer failure. This paper presents a non-intrusive PD detection strategy for a PWM voltages using high speed optical sensors for foil-type transformers to detect partial discharges in MF transformer's inter-winding insulation at PWM voltages containing high dv/dt switching transients due to SiC devices. PD inception and extinction characteristics are experimentally obtained in the lab using a hardware consisting of 3.3 kV SiC MOSFETs that generates PWM voltages with dv/dt up to 60 V/ns and switching frequency up to 50 kHz on foil winding specimens.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"17 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":"132276728","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}
