This paper presents the up-gradation of power quality with DSTATCOM connected in distribution system. The DSTATCOM employed for power quality (change for the better) is a multi-level (5-level) cascaded H-Bridge configured device which is capable of delivering leveled compensating signals which are later filtered. The power switches of multi-level configured DSTATCOM are pulsed using multi-carrier PSCPWM fashion to which character reference components are obtained from instantaneous power control method. The proposed system is competent to make up unbalance, power factor and harmonics insisted by three-phase balanced non-linear loads and unbalanced non-linear load types in the distribution system.
