- 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.
