Getting more from fluorescent lamps through resonant converters

摘要

It is pointed out that high-frequency resonant power converters make it possible to exploit tabular fluorescent lamps without electrodes. The authors outline a simple approach that puts this situation into perspective in the case of capacitively coupled lamps. A Class-E inverter which is suitable for the electrodeless operation is also described. Experimental results from a 16 W converter breadboard with the proposed circuit topology using 2.65 MHz and 13.56 MHz switching frequencies are discussed.
