Sliding Mode Control of DSTATCOM Using Seven Level Multilevel Inverter

In distribution system (DS), the majority of power consumption has been drawn in reactive loads. These loads are drawn in low power factor and therefore give rise to reactive power burden in the distribution system. So that DSTATCOM controller is used to compensate reactive power, correction of power factor and elimination of current harmonics. This paper presence the 7-Level Cascaded Hbridge Inverter as DSTATCOM for compensation of Balanced and Unbalanced Linear and Non-Linear Loads by using Level Shifted and Phase Shifted PWM techniques. The advantage of CHB Inverter is reducing the number of switches and thus switching losses.The simulation verification of the derived results are provided through a three-phase distribution static compensator (DSTATCOM) model. The application in the three-phase system has been shown through simulation studies
