Cascaded multilevel H-Bridge inverter based DSTATCOM for voltage compensation

This project proposes a Distribution Static Compensator based on cascaded H-Bridge multilevel inverter. The designed controller aims at achieving voltage compensation during load conditions. The voltage sag and voltage swell causes damage for the entire system. The proposed system consists of five levels cascaded H-Bridge multilevel inverter which uses a battery as a DC sources. If the voltage sag or voltage swell is present in the circuit, then the cascaded H-Bridge multilevel inverter compensates the voltage. Usually, the DSTATCOM is connected to the power networks at a Point of Common Coupling through a transformer where the voltage quality problem is a concern.
