  • Ballast circuit for gas discharge lamps
    Patent number: 7443105
    Abstract: A ballast circuit for a gas discharge lamp, having the capability to shift frequency after starting to reduce electromagnetic interference (EMI). Embodiments of the circuit contain an oscillator circuit that generates and supplies an oscillating signal and a time delay circuit, which generates a time delay to signal the oscillator to shift frequency. In embodiments of the circuit, the frequency shift is achieved by selecting different passive components used to generate the oscillator frequency.
