PWM and FCS-MPC in a Single Phase Converter with L Filter: An Extensive Comparison

Abstract

In this paper, an extensive comparison between the Phase Shifted PWM (PS-PWM) and the Finite Control Set Model Predictive Control (FCS-MPC) method is attempted. Particular emphasis is placed on the influence of proportional gain to the efficiency of PS-PWM. Furthermore, an analytical approach which facilitates the calculation of optimal proportional and integral gains of PS-PWM was developed. In addition, a delay compensation method applied in FCS-MPC and PS-PWM is proposed. Simulation results are provided to test the behavior of both modulation strategies considering several operational aspects both in steady state and in transient operation.
