Abstract

Wide-bandgap silicon-carbide (SiC) devices enable switching frequencies above 100 kHz. They keep high power density and fast dynamics. High-frequency operation also magnifies sampling-to-computation delay, parameter drift, and parasitic effects. These factors challenge the stability of Finite-Control-Set Model Predictive Control (FCS-MPC).This paper reviews three routes. The first is fast vector pre-selection. The second is explicit delay compensation. The third is online parameter/disturbance adaptation. We compare representative methods and reveal the trade-offs among computational complexity, stability margins, and robustness to thermal drift. We also note two engineering bottlenecks. One is model-error–delay coupling and the resource limit of FPGA-SoC platforms. The other is coordinated control in multi-module systems. Finally, we discuss future combinations of FCS-MPC with long prediction horizons, machine learning, and hardware acceleration. This research provides crucial theoretical support and practical guidance for the stable control of high-frequency power electronic systems. It holds significant value for promoting the industrialization of the application field of wide bandgap devices. By systematically analyzing the design bottlenecks of the integration of control algorithms and hardware platforms, this research has pointed out the innovative direction for the development of the next-generation highly reliable power converters.
