Harmonized strategy for breaking the striations in the fluorescent lamp

A harmonized strategy for breaking the striations in the fluorescent lamp i s proposed. The harmonized circuit (HC) presented is a dependent current so urce and is used to modulate the lamp current by making the amplitudes of t he even harmonics nearly the same as the neighboring odd harmonics. The tim e and frequency responses of the lamp current without and with HC are respe ctively simulated and experimented for describing the striation behavior. T he dimmer system with HC can actually provide better immunity from striatio n for the lamp during a wide dimming range from 10% to 100%. In addition, t he lighting efficiency increases up to 16.2%.
