Abstract
Various embodiments of a fluorescent lamp power supply are disclosed herein. In one embodiment, a power supply includes a power input connected to a pulse generator. The power supply also includes a filter connected to a variable pulse width output on the pulse generator and to the power input. The filter is adapted to substantially block at least one harmonic frequency component of the variable pulse width output and to substantially pass a fundamental frequency component of the variable pulse width output. The power supply also includes a power output connected to the filter, wherein an amplitude at the power output is related to the pulse width at the variable pulse width output.
