An Electronic Ballast for Electrodeless Fluorescent Lamps

Futoshi Okamoto; Hiroki Hasegawa; Kazurou Harada; Yoshiyuki Ishihara; Toshiyuki Todaka

We experimentally investigated an electronic ballast for electrodeless fluorescent lamps operated at 150, 200, and 400 kHz in order to achieve high efficiency, low cost, and low EMI. An efficiency of around 96% was obtained, and the EMI at 200 kHz was lower than that at 2.65 MHz. The EMI from lamps with the coil inside was lower than from those with the coil outside at the same driving frequency.
