摘要:
数字控制逐渐和电力电子应用紧密结合,功率因数校正是电子技术的一个重要应用.在高压大功率的应用场合,为了减少电磁干扰和提高系统的效率,研究了数字控制的有源功率因数校正(Active Power Factor Correction,APFC)的基本原理及实现方法,详细分析了在连续调制模式下的升压型有源功率因数校正技术整体控制方案.为了验证该方案的正确性,本文搭建了一台试验样机,实验证明了该功率因数校正电路可以稳定地将功率因数提高到0.99以上,并将总谐波畸变率降至5%以下,在结果中给出了实验的输入端波形.
Abstract:
Digital control is gradually closely integrated with power electronics applications, and power factor correction is an important application of electronic technology. In the application of high voltage and high power, in order to reduce electromagnetic interference and improve the efficiency of the system, the basic principle and implementation method of digitally controlled Active Power Factor Correction (APFC) are studied, and the overall control scheme of step-up active power factor correction technology in continuous modulation mode is analyzed in detail. In order to verify the correctness of the scheme, a test prototype is set up, and the experiment proves that the power factor correction circuit can stably increase the power factor to more than 0.99 and reduce the total harmonic distortion rate to less than 5%, and the input waveform of the experiment is given in the results.
