摘要：A ballast circuit for a gas discharge lamp, having the capability to shift frequencyafter starting to reduce electromagnetic interference (EMI). Embodiments of the circuitcontain an oscillator circuit that generates and supplies an oscillating signal and a timedelay 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 passivecomponents used to generate the oscillator frequency.
