摘　　要：介绍了一种临界断续导电模式的功率因数校正(PFC)技术,它应用Boost型电路,主要特点是通过控制固定开关的导通时间,使电感电流呈临界断续的三角波变化,其平均值随正弦波变化,这种功率因数校正技术可以使电路的功率因数达到0.99以上。A kind of power factor correction technology named DCM Boundary is mtroduced.It is applied in the carcurt of boost topology. the mam characteristic is controlling the on time and making the average current across the inductor change like sine wave. Using this technology can improve performance of the electrome ballast. The power factor is above 0. 99
