| 摘 要： | 介绍了一种用在大功率电除尘电源中的有源功率因数校正(APFC)技术,采用一种基于坐标变换的技术在电源输出端就对电流的波形畸变进行补偿,并通过数学推理得到APFC理想的控制点,可有效地抑制了注入网络的谐波电流.通过MATLAB对上述理论进行仿真,验证该技术对改善除尘电源输入电流波形畸变、提高输入功率因数的有效性.

| Abstract: | This article introduces active power factor correction (APFC) used in large power electro-static precipitation (ESP) power supply,whereby,based on coordinate transformation,current waveform distortion are compensated at the power output end,and ideal APFC control point can be obtained through mathematical reasoning,so that harmonic current injected into the network can be inhibited effectively.The above-mentioned theory is simulated through MATLAB,and its effective improvement of input current waveform distortion of the ESP power supply as well as raising of input power factor is verified. |
