Patent
Single switch electronic dimming ballast
TL;DR: An electronic ballast for driving at least one gas discharge lamp from a source of AC power which has a substantially sinusoidal line voltage at a given line frequency is presented in this paper.
Patent
Electronic ballast having improved power factor and total harmonic distortion
TL;DR: An electronic ballast for driving a gas discharge lamp includes a rectifier, a valley-fill circuit, an inverter having first and second series-connected controllably conductive switches having complementary duty cycles, and an independent cat ear power supply to provide power to the ballast control circuits.
