An Optimized AC Linear Current Regulation Technique for a Voltage Source Inverter

Current regulators for ac inverters including linear PI, hysteresis, deadbeat predictive regulators can be utilized both in synchronous and stationary frame. This paper introduces the optimization of AC current regulation in stationary frame using a PI regulator for a single phase inverter or symmetrical three phase inverter, minimizing the steady-state error. Also, the PR regulator is discussed here. MATLAB/Simulink is used to build the model and verify the results.This research was supported by BK21PLUS program through the National Research Foundation of Korea funded by the Ministry of Education
