Analysis and implementation of a high voltage pulse driver with energy recovery circuit for CNT-FE lamp

This paper investigates a high voltage pulse driver for driving carbon nanotube field emission lamp (CNT-FEL) based on a two-switch flyback topology. The proposed driver incorporates an energy recovery circuit to feedback the excess energy to DC bus, thus eliminating the arcing phenomenon caused by the traditional DC driving and improving the system efficiency. Analytical modeling, complete design considerations, and experimental results confirm the validity of the theoretical predictions by the proposed circuit architecture.
