In the proposed topology, the voltage multiplier and switched-capacitor are merged to enhance the voltage gain. This feature along with connecting the coupled inductors in series at the output stage increases the voltage conversion ratio. To reduce the input current ripple, two coupled inductors are connected in parallel for sharing the input current equally, resulting in low conduction loss as well as a smaller capacitive filter. To suppress the voltage ringing that stems from the energy stored in the leakage inductance of coupled inductors, the active clamp circuit is implemented in the proposed converter. By applying an integrated regenerative snubber, the leakage energy of coupled inductors not only is recycled to the output stage but also paves the way for soft-switching including zero voltage switching for switches and zero current switching for diodes. The operation modes, design consideration, and comparison verified by experimental results of a 1-kW laboratory prototype of proposed converter are presented. The switches and diodes are implemented using gallium-nitride (GaN) and silicon carbide (SiC) semiconductors, respectively.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124268061","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}

A few WPT standards have been established with frequencies ranging from kHz to MHz. MHz operation offers smaller size and higher tolerance to coil misalignment, and kHz operation offers higher efficiency and higher power rating. This paper presents a WPT architecture with new transmitter and receiver topologies that are reconfigurable for dual-band operation. On the transmitter side, we developed a novel architecture based on the reactance steering network (RSN) which can seamlessly compensate an arbitrary load impedance for radio-frequency (RF) power amplifiers. It can transmit power at two frequencies (kHz and MHz range) with decoupled power modulation. On the receiver side, we developed a reconfigurable dual-band rectifier that can achieve a power density of 300 W/inch3 at both 100 kHz and 13.56 MHz with very low component count. A dual-band reconfigurable WPT system comprising a dual-band transmitter and multiple dualband receivers has been built and tested. The RSN-based dualband transmitter can efficiently and simultaneously deliver 15 W of power to multiple receivers at both 100 kHz and 13.56 MHz.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129771573","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}

An N-to-1 TSAB is a hybrid converter derived from the N-to-1 Dickson switched-capacitor (SC) converter, with small ac inductors inserted in the flying-capacitor branches to achieve lossless (\"soft\") capacitor charging and discharging. In operation, a TSAB converter resembles the isolated Dual Active Bridge (DAB) converter but without the need for an isolation transformer. The TSAB family has several favorable characteristics, which lead to very high efficiency around nominal conversion ratio, including small ac inductors with near-trapezoidal low RMS currents, low voltage stresses, and zero-voltage-switching (ZVS) over wide load range. Moreover, the operation is robust with respect to component tolerances, and continuous voltage regulation can be achieved through simple phase shift control. Experimental results are presented for a 120 W, 48V-to-12V TSAB prototype, demonstrating a flat efficiency characteristic with 98.6% peak efficiency, and 98.0% full-load efficiency.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132691440","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}
