Abstract :
A high voltage full-bridge resonant inverter is proposed for driving carbon nanotube field emission lamp (CNTL). First, we construct an equivalent model of CNTL to exhibit its electric characteristics. Moreover, the high frequency sinusoidal driving strategy is employed to eliminate the arcing phenomenon caused by the traditional DC driving. And then the PLL feedback controller is used to stabilize the lamp luminance. Complete design considerations and mathematical model are detailed. All the experimental results agree with the theoretical predictions.
