| Abstract |
Light-emitting-diodes (LEDs) are commonly used for backlighting and lighting applications. For LEDs to be used as lighting or backlighting sources for vehicles, it is important to simplify the dimming scheme for LED drivers. Since the number of required LEDs varies with application, a single-ended primary-inductor converter (SEPIC) topology is suitable for the LED drivers to operate in a single battery system. In this paper, a SEPIC LED driver with a hybrid dimming scheme is proposed for vehicle lighting and backlighting applications. The proposed scheme reduces the wiring complexity of vehicles and the cost of LED drivers. |
