| 摘 要： | 提出了基于预测电流控制的电流控制算法，应用于数字控制的三相功率因数校正变换器。此算法可以简洁的实现电流内环，相应地减少了TMS320F240的程序占用资源；与预分解矩阵算法结合，只用一个定时器下溢中断就完成了所有算法。电流预测能实现三相输入电流的跟踪，便于电压环的设计，实现三相电压型PWM整流器的高功率因数。仿真和实验结果验证了预测电流控制器算法的有效性。

| Abstract: | A predictive current controller applied to three phase PWM rectifier is proposed. It can simplify the design of the current control loop and occupy less Time memory and interrupt in DSP TMS320F240. Together with the decomposition, the total algorithm can be implemented only with timer1 underflow interrupt subprogram. The predictive current controller helps to design voltage loop and the input currents track down the input voltages so well that the high power factor is achieved. Finally the simulated and experimental results are given to verify the proposed predictive current controller. |
