Active offset for power factor controller |
摘要 |
A switch mode power supply for a ballast having a power factor controller and providing a regulated D.C. output voltage. The controller is responsive to a control input signal which includes a sensed signal added to a varying offset. The sensed signal is representative of the current flow through a switching device of the power supply. The offset is varied based on the regulated D.C. voltage output.
