| 中文摘要 | 为了利用临界连续导电模式功率因数校正器(PFC)高效的优点,将其应用到较大功率场合,提出一种用于临界连续PFC的单周期控制策略。采用开关频率和采样频率可变的方法,利用单数字信号处理器实现了3个临界连续PFC变换器的并联交错运行。提出的针对临界连续PFC变换器的单周期控制器无需对开关的高频峰值电流、电感电流过零点进行检测与判断,简化了临界连续PFC变换器的控制。实验结果表明:该方案可实现临界连续PFC变换器输入电流和输出电压的有效控制,可在保证高的输入功率因数同时,获得稳定的直流输出电压。; This paper proposes a one-cycle controller for a critical conduction mode(CRM) power factor correction(PFC) converter,and with variable switchingfrequency and variable sampling-frequency used to have three CRM PFC modules operating in paralleling and interleaving mode with a single digital signal processor(DSP).The one-cycle controller for the CRM PFC needs not detect the peak switching current and judge the zero-cross of the inductor current,so it can simplify control of the CRM PFC converter at a great extent.Experiments show that the controller provides very effective control of the current input and the voltage output,so it can achieve stable output voltage with high input power factor. |
