摘要:The need of implementing a second local oscillator beside the drive oscillator,for timing the different phases of the starting process of a half-bridge or bridge stagedriving an external load such as a fluorescent lamp, is avoided by employing a timingcounter to count the number of oscillations produced by the drive oscillator and adigital-to-analog converter for controlling the frequency of oscillation of the driveoscillator.
