Providing an additional direct energy transfer path can decrease its size. Parallel forward-flyback converters offer such functionality and outperform forward converters with regard to PFC functionality. A balanced forward-flyback converter is a variation on this kind of parallel converter. The forward and flyback sub-converters share a transformer winding and an additional balancing capacitor enables even better AC line voltage utilization. This paper starts with an in-depth analysis of the balanced forward-flyback converter, and introduces ten operating modes in which this converter can operate. A boundary-conduction mode (BCM) controller for the magnetization current is developed and presented, and through simulations the PFC performance of the converter is tested with a constant switch on-time controller. Moreover, a prototype is designed and built with both a dissipative R-C-D snubber and two-switch clamp configuration. Experimental results from the 100W/120–373V AC/DC prototype were obtained to prove the converter operation and BCM controller concept. The balanced forward-flyback converter in BCM offers good PFC performance and manages a THD of input current between 1.69% and 4.38%.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114425582","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}

Although a number of grid integration technologies suitable for BD-IPT systems have been proposed in the past, a comparison between these technologies is yet to be presented. As such, this paper intends to provide a comparative overview of 3 different grid integration technologies employed by BD-IPT systems. These include, the conventional implementation, matrix converter based implementation, and an active filtering based implementation. A system level overview of each technology, mathematical models and guidelines for sizing energy storage components are presented. Simulation results of each system rated to 3.3 kW are also presented. With the aid of simulations, the functionality of each grid-integration technology is investigated and compared. A detailed loss analysis and an investigation in to effects of component sizing on system performance are also presented.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123503810","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 this paper, a three-port, dc-dc-ac Solid State Transformer (SST) is presented that can control the magnitude and direction of power transfer between a battery, a dc bus and the ac grid. The proposed SST features a low magnetic component count, has high power density, high efficiency and provides galvanic isolation between all three ports. The presented topology is operated with a fixed switching frequency and is phase shift modulated. In this paper, a mathematical analysis of the proposed SST is presented along with its sensitivity to parameter variation. The requirements for soft switching is derived and it is demonstrated that the converter can soft switch over large input voltage variation. The modulation parameters are optimized so that the high frequency link currents are minimized while soft switching is maintained. Additionally, in the simulation results, the ac grid current is modulated so that no Power Factor Correction (PFC) circuitry is required.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124432815","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}
