一种用于LED照明的Sigma-Delta控制集成多电平变换器

LEDs have finally emerged as the dominant lighting technology. As such, the lighting industry values power converters that have high efficiency, unity power factor, minimal flicker, dimming, low cost, and a small form factor. This paper presents an integrated circuit (IC) LED driver that is designed to achieve these goals. It introduces multilevel converters with sigma–delta modulation to the powe...
