Unified Power Quality Controller
Unified Power Quality Controller is the final answer for your power quality problems. It will provides voltage stabilization and harmonic correction for voltage wave form and corrects power factor to unity including non linear current waveforms. Basicaly it uses two PWM four quadrant inverters for power quality corrections. One delta inverter of small capacity in series for voltage regulation and voltage waveform harmonic correction and one full rated inverter connected in parallel for power factor correction and current harmonic correction for non linear loads. Both inverters are connected to a common DC link voltage.
The proposed topology is tested using pspice and found satisfactory. Hardware implimation is going on. I will publish hardware details soon.
