Developed a high power factor fluorescent lamp ballast with M S C60028 integrated power factor correction chip. The whole system consists of control circuit, boost circuit and inverter circuit. The experimental results show that the waveform distortion of the circuit is less than 5% and the power factor cosφ is 0.99, which can improve the operation quality of the power grid.
