三相PFC电路的新型控制算法研究

A novel control method in three-phase power factor correction

在大功率三相整流领域,由于电路功率大、非线性高,传统的控制技术不能有效地达到控制效果。在总结单相有源功率因数校正研究成果的基础上,提出新的三相功率校正的控制方法-模糊自适应PID控制方法。并在Simulink建立仿真模型,验证了该方法的实用性和先进性,达到了理想的结果,在大功率整流设备中具有一定的应用价值。

In the filed of three-phase power factor correction, the traditional technology can not control the system efficiently because the circuit power is high and the system model is nonlinear. On the base of the research result of single-phase power factor correction, the new control method was put forward, namely, fuzzy-PID in three-phase PFC. By means of building the simulation model in Matlab, it is proved that the way is functional and effective. This experiment reached the expected result and it＇ s very worthy to use in high-power rectification equipment.
