摘要
提出一种新的高功率因数的开关变换器，该变换器采用单级结构、单一占空比ＰＷＭ控制模式，完成功率因数校正和输出电压调节双重功能；并对该变换器的工作过程进行了详细分析；最后给出该变换器在电子镇流器电路中的应用。
A novel switching converter with high input power factor is put forward. This type of converter, with a single stage structure and single duty ratio PWM control mode, can implement a dual function of power factor correction and output voltage regulation. High power factor and low input current distortion are easily obtained without complicated duty cycle modulation method. Meanwhile, detailed analyses on the converter's working procedure are made, and application of the converter to the electronic ballast circuits is presented additionally with experimental results for verification.
