This dissertation proposes a new starting profile with some modifications to the definition of American National Standards Institute (ANSI) to interpret the starting process of fluorescent lamps driven by high- frequency electronic ballasts. To identify the times of preheating, ignition, and steady-state, the staring transient waveforms of lamp voltages as well as the lamp currents are scrutinized from the experiments on a diversity of ballasting techniques. A glow-to-arc transition is considered to account for the stage between glow discharging and a stable lamp arc. In addition, the filament preheating is not limited to the constant voltage but can be current preheating which is more commonly used in commercial products. By the new definition, the glow current and the glow-to-arc current can be calculated to evaluate the lamp starting performance. The applicability of the starting profile is confirmed experimentally by the instant-start, preheat-start, rapid-start, modified rapid-start, and programmable rapid-start schemes.
