Abstract

An LC-filtered neutral-point clamped (NPC) converter is commonly used in distributed generation, uninterrupt- able power supplies and dynamic voltage restorers. A multiobjective modulated modelpredictive voltage control scheme is proposed to control the load voltages and neutral-point voltage of an LC-filtered NPC converter. In this work, the load voltages and converter currents are controlled simultaneously to improve the load voltage quality. An exact discrete-time model of power conversion system is used to predict the future behavior of state variables. These predictions are evaluated by a triple-objective duty-cycle optimized cost function. The three stationary voltage vectors corresponding to the optimal cost function are synthesized by the space vector modulation. The performance of the proposed control scheme is verified through MATLAB simulation results with linearand nonlinear loads. The results indicate fixed switching frequency operation, fast transient response, and low steady-state errors.
