Abstract:	摘要： This paper presents a LED driver for VLC. The main purpose is to solve the low data rate problem used to be in switching type LED driver. The GaN power device is proposed to replace the traditional silicon power device of switching LED driver for the purpose of increasing switching frequency of converter, thereby increasing the bandwidth of data transmission. To achieve high efficiency, the diode-connected GaN power transistor is utilized to replace the traditional ultrafast recovery diode used to be in switching type LED driver. This work has been experimentally evaluated on 350-mA output current. The results demonstrate that it supports the data of PWM dimming level encoded in the PPM scheme for VLC application. The experimental results also show that system’s efficiency of 80.8% can be achieved at 1-Mb/s data rate. 其他題名： Sci Rep 出版者： London: Nature Publishing Group UK 出版日期： 2016-08-08 出處： Scientific reports, 2016-08, Vol.6 (1), p.30991-30991, Article 30991 資源來源： Springer Nature Link 版權： The Author(s) 2016 版權： Copyright Nature Publishing Group Aug 2016 版權： Copyright © 2016, The Author(s) 2016 The Author(s) 識別號： ISSN: 2045-2322 識別號： EISSN: 2045-2322 識別號： DOI: 10.1038/srep30991 識別號： PMID: 27498921
