Model Predictive Control of An Embedded Enhanced-Boost Z-Source Inverter

This paper proposes a model predictive control strategy for an Embedded Enhanced-Boost Z-Source Inverter (EEB-ZSI). Due to many passive components and non-linear power devices in the EEB-ZSI, the closed-loop control with proportional integral (PI) controllers based on the small signal modelling is impractical. However, the proposed model predictive control strategy can achieve closed-loop control in terms of accuracy and dynamics, where the complicated modeling is not necessary. In the proposed method, only two capacitor voltages and two inductor currents are considered due to the symmetry. Simulation results are provided to validate the performance of the proposed control strategy.
