The proposed converter can realize the ZVS operation of the power factor correction (PFC) circuit’s power switches by sharing MOSFET switches of PFC circuit and full-bridge LLC resonant converter. Different from previous quasi-single-stage integrated AC–DC converter [7]– [12], the topology’s stable output voltage and the bus voltage can be simultaneously independently achieved. Moreover, the proposed converter possesses with intrinsic voltage-doubler PFC characteristic, which is suitable for high output voltage applications. The detailed operation principles for the proposed converter are analyzed and discussed. The feature of the proposed topology was demonstrated using PSIM simulation and a hardware prototype.

This paper proposes a simple to implement design approach for LLC dc-dc resonant converter suitable for operation under wide input voltage and load range for fixed output voltage applications. For such applications, selecting a design with low inductance ratio (K) and high-quality factor (Q) ensures narrow switching frequency variation but at the cost of efficiency and power density. However, maximizing power efficiency throughout the required range of line and load conditions with output voltage regulation requires optimal selection of K and Q. The proposed design approach is compared with two other existing design approaches and tested on an experimental prototype of 300W LLC converter for 2:1 input voltage range (20-40V). The proposed design shows rated efficiency improvement of 3% over existing methods.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127009068","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 management has become a key issue for the next generation of data centers. 48 V step-down converters are often required in server, telecommunication and automotive applications. Using resonant topologies such as LLCs allows to obtain ZVS (Zero Volt Switch) turn-on for all the switches over the entire load range using magnetizing current, yielding high efficiency. Recently a non-isolated, fixed ratio DC-DC solution defined as switched tank converter was proposed for this application, followed by a different 48 V to 12 V implementation. In this paper a configurable, dual-output, non-isolated DC-DC resonant topology is investigated. A configuration yielding 10:1 and 5:1 output rails is explored in detail with two converter prototypes from the 48/54 V input bus, achieving high power density, high efficiency and a low profile. Experimental results for a very-low-profile 200+ W prototype module provide to show the effectiveness of the discussed system. More results, comprising a 500 W module, will be provided in the final paper.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130649792","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}

Among existing bidirectional solutions, bridgeless totem-pole arrangement has been of great interest to both academia and industry due to its advantages of enabling ultra-high efficiency, i.e. above 99%, at low complexity. However, until now most research and development have mainly focused on AC/DC power factor correction (PFC) applications of the bridgeless totem-pole topology with very little effort to understand the practicality and performance of the converter in generation mode, i.e. DC/AC power inversion. Therefore, this article discusses the feasibility of the 3-level bridgeless totem-pole arrangement used as a DC/AC inverter in either islanded or grid-tied operation. This work is experimentally validated by a 3kW bidirectional PFC/Inverter prototype in a compact format of 41mm x 302mm x 1U with peak efficiency exceeding 99% at 230V for all operating modes.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121206218","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}
