Model predictive control (MPC) has become an attractive solution for power converter control due to its superior dynamic performance, simplicity, and one stop solution for multi-objective systems. Among all the existing MPC techniques, optimal switching vector MPC (OSV-MPC) is intuitive and utilizes the discrete nature of power converters. By nature, basic OSV-MPC generates variable switching frequency which causes poor THD, high switching losses, difficulties in filter design, and ripples in the control parameters. To overcome the above mentioned issues with variable switching frequency, fixed switching frequency based OSV-MPC algorithms were reported in the literature for current control applications. However, the application of fixed switching frequency methods for voltage control is limited in the literature. So, this paper discusses the applicability of existing fixed switching frequency methodologies to control load voltage for stand alone applications. Basic three-phase two-level voltage source inverter with LC filter is used for a case study. Simulation results are included for different OSV-MPC fixed switching frequency methods using MATLAB®/Simulink. Harmonic performance, transient performance, and computational burden have been discussed and compared with the conventional OSV-MPC. © 2019 IEEE.
