Abstract
- This letter proposes a novel current-fed parallel-resonant dc-ac inverter with zero-current switching (ZCS) for cold-cathode fluorescent lamps (CCFLs). The leakage inductance of the transformer is integrated within the resonant tank in order to reduce the voltage spikes across the switches. A laboratory prototype is implemented to drive a 617 mm/7W CCFL. Experimental results indicate that the switches of the proposed resonant inverter are operated under the ZCS condition, and the efficiency is approximately 86.8%. The lamp voltage is about 977 Vrms and the lamp current is 7 mArms. [ABSTRACT FROM AUTHOR]
