The rapid development of a three-phase grid-forming micro-source inverter

This paper takes the rapid development of a three-phase grid-forming micro-source inverter as the research purpose. Sliding mode control (SMC) and PI control strategies are adopted synthetically to implement the dual closed-loop controller. Firstly, Simulink model is built according to the actual inverter development condition. Simulation results demonstrate the effectiveness of the proposed algorithm. And then, the control codes are generated automatically based on the model design method. With the generated controller codes, it realizes the rapid development of a proposed GFI inverter. The hardware experiments are presented in the paper to demonstrate that the developed grid-forming micro-source inverter performs good robustness property under different load conditions and parameter uncertainty scenario.
