Abstract
Model Predictive Control (MPC) method offers advantages of easy implementation and fast dynamics. However Model predictive control method has variable switching frequency, which makes design of the output filter difficult for power converter. Despite the problems of MPC algorithm, there are little methods to fix the switching frequency using MPC algorithm in power converter. Therefore, this paper proposes constant switching frequency with MPC algorithm, which method simply selects the optimal voltages and divides the optimal voltages in one-sampling period. The performance is proved comparing to the conventional method and carrier based method in experimental results with average switching frequency for single-phase VSI.
