Control of input current harmonics and output voltage of three-phase voltage source PWM rectifier using Model Predictive Control

This paper makes a detailed analysis on the principle and characteristics of Model Predictive Control (MPC) applied to three-phase half-bridge active rectifier. Model predictive control has merits of forecast and real-time optimization. MPC controller computes the optimal space vector of input voltage to the PWM rectifier in the dq frame and then this desired space vector is modulated via space vector pulse width modulation (SVPWM). The simulation results from Matlab/Simulink illustrate the flexibility and effectiveness of MPC-SVPWM approach in harmonic suppression and unity power factor.
