Abstract
A gas discharge lamp control circuit includes a series circuit formed by first and second AC input terminals, an inductance and first and second lamp terminals. An ignitor circuit is coupled to the series circuit and selectively couples and decouples at least a portion of the inductance in parallel with the first and second AC input terminals to generate a flyback voltage in the inductance.
