The characteristic comparison of power factor correction circuits for electronic ballasts

In recent years, various power factor correction(PFC) circuits for the electronic ballast have been proposed. And these circuits have difference characteristics each other. We have researched several PFC circuits of them. And operational principles and characteristics of PFC circuits are compared by the cost and the electrical performance. Finally, we established the reference for the evaluation of PFC circuits with performance and the price.
