Abstract
The present invention discloses a system and method for active power factor correction and current regulation in led circuit. The system () used in the LED driver circuit performs active PFC and current regulation through the dynamic input current wave shaping by limiting peak currents. The dynamic waveshaping scheme is realized through hardware and firmware and is used to strike an optimal balance between current accuracy, Power factor, THD and peak inductor currents. The system () is versatile enough to improve PF and current accuracy in LED circuits and indimmers circuits.
