Model Predictive Control with Variable Virtual Voltage Vectors for Isolated Matrix Rectifier

Abstract— This paper introduces a novel model predictive control (MPC) method with the variable virtual voltage vectors (VVs) applied to the isolated matrix rectifier (IMR) in the power conversion system. This control method solves the problem that the switching frequency is not fixed in the conventional MPC and improves the dynamic response capability and robustness. The IMR is simplified by the idea of decoupling, which realizes the flexible and independent control of its bidirectional switches. Considering the actual industrial production conditions and parameter errors, the position of the virtual VVs can be adjusted. Simulation results verify the effectiveness of the proposed method, showing excellent static and dynamic performance.

Index Terms— isolated matrix rectifier, model predictive control, variable virtual voltage vectors, decoupling.
