Abstract：The electrolytic capacitor is the key component that limit the lifetime of AC-DC light-emitting diodes(LEDs) driver. Therefore, eliminating the electrolytic capacitor in LED driver has been a key problem. In the recent years, a great number of solutions have been proposed based on control strategies and topology optimization. In this paper, the research status of eliminating electrolytic capacitor in AC-DC LED driver is detailed in terms of control strategies and optimized topologies. The fundamental thoughts on the methods of eliminating electrolytic capacitors in AC-DC LED drivers based on control strategies and topology optimization are summarized. The technical principles of the existing methods are presented, including application features. Finally,we propose application advice and the direction of research based on the performance of different technologies for eliminating the electrolytic capacitor.
