Abstract

A novel DC bus voltage estimation algorithm with inherent cancellation of feedback voltage ripple is presented in this work. Design issues are discussed and simulation results are presented. Apart from reduction of output voltage sensor, the proposed estimation algorithm also eliminates twice the line frequency ripple from the feedback path allowing a voltage controller bandwidth comparable to line frequency, suitable for most front-end power factor corrected (PFC) converter applications.
