Predictive Power Control of AC-DC Matrix Converter Model

The non-isolated AC-DC matrix converter has the advantages of high efficiency and high power density. In order to improve the quality of the output power of the AC-DC matrix converter, this paper proposes to combine the virtual space vector with the model predictive power control (MPPC), establish the cost function with power as the control objective, and introduce the active damping current, which can effectively improve the control accuracy of the system and reduce the total harmonic distortion rate of the input current, and the simulation results validate the effectiveness of the proposed control strategy.
