摘　　要：给出了一个基于集成自激振荡变换器与Buck-Boost功率因数校正电路的单级电子镇流器.功率开关管的控制信号是通过谐振电路中串接的饱和变压器获得的,用铁芯饱和来控制两个开关管控制信号之间的死区时间.由于没有专用集成电路控制镇流器,所以这种镇流器和典型的两级电子镇流器相比成本较低,实验证明其电路可行.This paper gives a single-stage electronic ballast based on the integration of self-excited oscillation converter and Buck-Boost power factor correction circuit.Controlling signals of Power MOSFET is obtained from the resonance circuit of the combination of saturated transformer.The iron core is saturated to control two Power MOSFET control signal dead time.Since no special integrated circuit control ballast,and compared with typical two stages of electronic ballast,the ballast is low cost and the experiments show that the circuit is feasible.
