A boost PFC ac-dc converter that is suitable for digital
processor control has been designed. Calculations that led to
selection of circuit components have been presented. Standard
procedure has been followed to design compensators for both
the current and voltage loops. The whole design has been
tested by means of simulation using Powersim power
electronics and drives simulation package. Even though the
simulator restricted the implementation of the control law, the
results are encouraging. There is indication that if a practical
system is realized with the freedom of practical digital
processor programming, excellent results will be achieved.
