Abstract
This paper proposed a solid-duty-control technique in the boost converter to keep a constant duty control to reduce dip voltage during load transient period. Besides, due to variable transient enhancement controller, fast transient response is achieved. The proposed SDC technique can provide a stable and regulated output for edge-lit LED backlight systems. Compared to conventional design without any fast transient technique, experimental results show the undershoot voltage and recovery time are improved 30% and 80%, respectively.
