Aim of this paper is to reduce the cost of power quality converter. Numbers of converter are used to control the power quality i.e 12-switch converter, 9-switch converter etc. Nine switch converter has an advantage that is less of number of switches as compare to 12 of the back-to-back converter. But some restrictions in the total attainable amplitude at its outputs, depending on the phase shift between its two terminal sets. With an appropriate design control scheme for nine-switch converter, it show favorable improvement of overall power quality & justify its role as a power conditioner at a reduced semiconductor cost. The proposed power conditioner presents a only eight switches, transformer-less hybrid filter, four-switch two-leg inverter and a six-switch dynamic voltage restorer & it is capable for voltage sag mitigation and another unit for current harmonic compensation.
