A new active LED driver with high power factor (PF) and low total harmonic distortion (THD) compatible with a conventional rapid-start ballast is proposed. A dedicated LC compensation circuit is attached to the ballast to increase the PF and lower the THD of the source current. A boost converter is used for regulating the LED current, however its duty cycle… CONTINUE READING
