Abstract

Hybrid ballast for field emission lamp with CNT (carbon nano tube) emitter is proposed. Hybrid ballast consists of a high voltage dc part and hi-polar pulse generation part. Field emission lamp with CNT lamp is composed of three electrodes (anode, gate, and cathode). High voltage dc part is for anode and gate and hi-polar pulse generation part is for gate and cathode in CNT triode respectively. The experimental results demonstrate that the proposed topology is good for driving CNT lamp. To protect the lamp and ballast, OCP (Over Current Protection), OVP (Over Voltage Protection), and OTP (Over Temperature Protection) are added and the experimental results demonstrate that the proposed method is good for driving field emission lamp with CNT emitter.

본 논문에서는 전계방출 원리를 이용하여 이미터로서의 성능이 뛰어난 탄소나노튜브 (Carbon Nano Tube)를 이용한 전계방출 면광원용 안정기를 제안한다. 안정기는 고전압 직류전압 부분과 양극의 펄스를 생성하는 부분으로 구성되어 있다. 탄소나노튜브를 이용한 전계방출 램프는 3가지의 전극 (애노드, 게이트, 캐소드)으로 구성되어 있는데, 애노드와 게이트 사이에는 직류 고전압이 공급되고 게이트와 캐소드 사이에는 양극의 펄스가 공급된다. 램프 및 안정기를 보호하기 위하여 과전류, 과전압, 과온도에 대한 보호 기능을 추가하였고, 실험을 통하여 제안된 방식이 탄소나노튜브를 이용한 램프 구동을 위한 적합함을 검증하였다.
