Abstract
AbstractThis paper presents a DC voltage control scheme for a single‐phase PFC converter which can realize both the harmonic suppression of the input current and the fast dynamic response to the DC voltage. Instead of using a constant DC voltage reference, the controller calculates a fluctuating DC voltage reference, having the frequency at twice the source frequency. In the calculation of the DC voltage reference, the circuit parameters are used. Since the parameter errors may cause an error in the DC voltage reference, parameter identification is also described. The effectiveness of the proposed control algorithm has been verified experimentally. © 2002 Wiley Periodicals, Inc.
