Abstract
In this paper, the predictive current control is applied to the matrix converter-based novel power electronic transformer(MC-NPET). In order to control the output voltage, PI control is added. The proposed method aims to regulate the output voltage of the novel power electronic transformer and correct the input power factor. By discretizing the input and output model of novel power electronic transformer to predict the value of the controlled variables at the next time. By using a predictive cost function, the best switch combinations to be applied to the next time. The proposed cost function takes both the output current and the input power factor into account. This paper also analyzes the stability of the system and analyzes the system output voltage under different load conditions. Finally use MATLAB/Simulink to verify the method.
