Abstract

Robust PFC converter which can covers the dynamic characteristics changes of load changes and duty ratio changes with only one controller is needed. In this paper, the robust digital controller for suppress the change of step responses and variation of output voltage in the load sudden changes with high power factor and low harmonic is proposed. Experimental studies using Microcontroller for controller demonstrate that this type of digital controller is effective to suppress variations and power factor improvement.
