Predictive current control in a single phase PFC boost rectifier

Abstract

Predictive control has become a promising alternative to control power electronics devices, due to the continuous development of digital processing technologies. Predictive control methods exhibit high dynamic response being well suited to system that require tracking capabilities. In this paper a power factor correction rectifier, that requires a current control with a rectified sinusoidal reference, is controlled using three methods: i) Linear control ii) Hysteresis control iii) Predictive control. All these controllers are implemented on a digital platform. Simulation results show that predictive control offers a valid alternative to the others proposed control methods in terms of input current harmonic content and input power factor.
