摘要
提出了一种基于DSP TMS320F2812数字控制的平均电流型交错并联升压型功率因数校正(Boost PFC)变换器。重点提出了150 kHz/Phase开关频率下的控制算法与改进的采样算法,并对电压、电流双环数字控制回路进行分析与PI补偿设计。基于Matlab/Simulink对并联交错Boost PFC数字控制系统进行建模仿真,并制作300 W输出功率的样机,成功对Boost PFC控制系统进行了验证与实现。
A digital controlled interleaved Boost Power Factor Correction(PFC) converter is presented with the method of average current control based on the DSP of TMS320 F2812. The control algorithm and the improved sampling algorithm with 150 k Hz/phase switching frequency are put forward. The voltage and current double closed-loop digital control circuit are analyzed and executed PI compensation design. The modeling and simulation is performed by Matlab/Simulink for interleaved Boost PFC numerical control system. A 300 W output power of the prototype of the Boost PFC control system is implemented and verified.
