Abstract :
In this paper, an approach for the design of a digital controller for a PFC pre-regulator is proposed. The controller is modified to account for large control periods and computational delays, and can therefore be implemented on processors with few available computational resources. Results show that, even with a very low control rate, system specifications can be met using the proposed technique
