New configuration of multi-functional grid-connected inverter to improve both current-based and voltage-based power quality

In this paper, a new configuration of a multi-functional grid-connected inverter is proposed to improve both voltage-based and current-based power quality issue. By implementing bidirectional switches using semiconductor devices, a multi-functional grid-connected inverter can be connected in series or parallel to the grid and provides three modes of operation. This paper presents the control scheme of a multi-functional grid-connected inverter in each operating mode, the realization of bidirectional switches, and simulation results of the proposed multi-functional grid-connected inverter.
