Experimental design of a finite state model predictive control for improving power factor of boost rectifier

Abstract

this paper proposes a simple, low-cost, and powerful controller based on finite state model predictive controller (FS-MPC) for a single-phase boost power factor correction (PFC). The proposed controller can achieve high static and dynamic performances under different loads or DC link voltage variations. The proposed method works in the discrete time domain with a minimum time delay and capable of achieving a unity power factor in AC current. Moreover, in order to examine and evaluate the merits of the proposed method in real-time, an experimental test bench has been built around dSPACE 1104. The obtained results are very significant and much better compared to latest works.
