Abstract
This paper presents Load Current Control based on Luenberger Observer for Three-Phase Power Converter SVPWM with current regulation. The use of observer is intended to replace the use of dc current sensor, so it eliminates the nonlinearity problem and drop voltage caused the sensor. This research develops a controller to improve the time response of the dc output voltage of the three-phase power converter based on load current estimation. The simulation results show that overshoot the output voltage on load change from full load to 50% full load is about 3% with settling time 0.03 sec.
