A supercapacitor-based power conditioning system for power quality improvement and uninterruptible power supply

A power conditioning system (PCS) which uses a supercapacitor bank as energy storage device is proposed as a viable solution for improving the quality and the reliability of the electric energy supply. Several tasks can be performed at the same time, such as reactive power compensation, current harmonic reduction, and smoothing of pulsating loads. Moreover, the PCS can operate as uninterruptible power supply (UPS) during short time interruptions of the grid supple.
