A simple design method for power factor correction (PFC) boost converter is presented in this article. Model based cascade controller design is presented for the control of PFC boost converters. Detail discussions in the setting of bandwidth for the current loop and voltage loop have been given. Finally, a deadband relay is introduced in the voltage loop to improve the disturbance rejection and speed of response of the PFC boost converter. Circuit implementation of the proposed control scheme is presented and experimental results are included to demonstrate the effectiveness of the proposed design scheme. The resultant power factor is over 0.99, the total harmonic distortion of supply current is less than 2.9% and the efficiency of the converter is 93% at full load.
