Abstract:
The present invention discloses an electronic ballast with dimming control from power line sensing for a fluorescent lamp, comprising: a control voltage generator, used to generate a control voltage according to a switching count of a power line; an oscillator, used to generate an oscillating signal, wherein the oscillating signal is of a fixed frequency and has a rising voltage portion and a falling voltage portion; and a comparator, used to generate a high side gating signal according to voltage comparison of the oscillating signal and the control voltage.
