| Abstract: | To uncontrolled rectifier, in this paper, at first, the advantages and disadvantages of the three passive power factor correction(PPFC) methods are analyzed. Secondly, the principle of active power factor correction (APFC) method isdiscussed indetail. At last, a practical circuit with low harmonic distortion and high power factor is given, and UC1854 IC is the main device of this circuit. Using APFC method, the AC line power factor is nearly unity and the harmonic distortion is much lower than the PPFC method. APFC method will play an iportant role in economizing energy and improving power network quality. |
