A Novel Digital PCM-V2 Control Method for Active Clamp Flyback Converter to Realize Fast Output Dynamic Response
2020 IEEE Applied Power Electronics Conference and Exposition (APEC)(2020)
Abstract
Active Clamp flyback converter (ACF) is a good candidate to replace the traditional flyback converter to be used in high frequency small power applications. Due to the circuit delay and intrinsic characteristic, PCM controlled ACF converter has a slow output dynamic response. Therefore, by associating the PCM with V
2
control method, a novel PCM-V
2
control scheme is proposed to improve the output dynamic response of PCM controlled ACF converter. The control scheme is illustrated, and the modeling strategy of the proposed PCM-V
2
control is given. After comparing the frequency response curve, the presented PCM-V
2
control method has a larger bandwidth than PCM control. To verify the effect of the proposed method, a 65W 20V output ACF converter is simulated ant tested. The simulation and experimental results between PCM-V
2
and PCM control are compared and presented. The results show that the output dynamic response of the proposed PCM-V
2
is faster than PCM control method in ACF converter.
