abstract

• In this paper, a control scheme for power factor correction (PFC) and output voltage regulation of an AC-DC boost power converter based on average current-mode control is presented. The proposed methodology relies on the design of two feedback loops; A non-linear inner loop for current tracking based on passivity-based control, as well as, an outer loop to generate a suitable desired value for the current using a proportional-integral (PI) action on the output voltage an its reference. Also, based on Immersion and Invariance theory, an uncertainty estimator is constructed to compensate parametric uncertainty and parasite elements in the passive elements of the converter. © 2019 IEEE.
