Abstract :
This paper presents a LED(light emitting diode) backlight driving system for automobile panels. A new scheme is presented and compared to the conventional scheme, and the simulation model for new scheme is presented and used to simulate the system. The study indicates the necessity of a technique for current equalization when using parallel LED arrays system.
