Abstract

This paper presents a comparative study between proportional integral (PI) and type-II compensation techniques, aiming at achieving high power quality as well as high bandwidth to enhance the dynamic performance of an H-bridge power factor correction (PFC) converter. The conventional PI compensator has a limitation in terms of the tradeoff between the input current reference tracking accuracy and the control loop bandwidth. Attenuating high frequency components in the input current requires a smaller bandwidth, which potentially can degrade the input power factor. Introducing an additional pole in type-II compensator helps to achieve both the requirements simultaneously as well as to reduce the inductor core loss due to reduced current ripple. As verification to the proof-of-concept, a hardware prototype for single-phase H-bridge PFC is built and tested upto 700 W. Incorporating type-II over PI compensator results in an improvement in total harmonic distortion from 6.8% to 4.2% and increase in efficiency from 98.2% to 99%, as exhibited by the experimental results.
