A Survey on Efficient Converter Driver Techniques for LED LIGHTING Applications

This review article focuses on various proposed LED driver technologies and different converter topologies which will help to increase efficiency, reliability, and lifespan of lighting systems. These classifications of LED drivers are presented for the both AC and DC voltages and are described evidently. The different methods to balance the currents at the output side of the driver, its pros and cons are explained in detail. This paper gives a detailed overview about the various power conversions and different control strategies like electrolytic capacitor less, soft switching, PWM dimming, current balance techniques to enhance the performance of LED drivers. The main goal of this paper is to give correct awareness to choose suitable LED driver for various smart lighting applications.
