In this paper, a pulse width modulation(PWM) method to reduce the fluorescent lamp current crest factor of the valley-filled power factor corrected(PFC) electronic ballast is presented. The proposed method controls switching duty cycle by feeding forward the dc-link voltage waveform of valley-filled PFC, restraining the lamp peak current and improving the(More)
