At the Department of EEE, GCE Kannur we have the following hardware setup.

1) Grid Connected Three Phase Inverter with Power Quality Improvement

The complete system was assembled in our lab using Semikron inverter module (three phase), LEM sensors (voltage and current measurement), 6N136 based gate drive, interfacing inductor and RC ripple filter. The system can operate as a DSTATCOM (providing power quality improvement) or as a renewable energy based inverter (active power injection + power quality improvement). The variety of local loads can be connected. (Non linear, RL, combined). The complete system is controlled using dSpace MicroLab Box. For the control purpose, Matlab/Simulink and Controldesk softwares are used.
