Model Predictive Current Control for High-Frequency Link Matrix DC/AC Converter with Loosely Coupled Transformer
the isolated single-phase DC to three-phase AC matrix converter has attracted significant research attention due to its advantages of low loss
simple topology and modulation. PI control is widely used in industrial manufacturing
but the increase in control target error and environmental factors will lead to decline of control system accuracy. We introduce a finite-control-set model predictive control (FCS-MPC) to predict the d- and q-axis currents in a high-frequency link matrix DC/AC converter (HFLMC) with a loosely coupled high-frequency transformer (LCHFT). The modulation and commutation modes of the HFLMC are introduced
transmission power of the HFLMC with air gap is given
and the output side compensated predictive model is also established. Design of LCHFT is given. The coupling coefficient of LCHFT under different air gap affects transmission efficiency. Finally
experiment results on a 300 W prototype verify correctness of the theoretical analysis and simulation.
