The proposed DVR is implemented using multilevel inverter topology with isolated dc energy storage. The phase shifted PWM technique is described to generate firing pulses to cascaded inverter. The proposed controller adopts itself to the sag and provides effective means of mitigating the voltage sags with minimum harmonics at the utility end. The proposed concept was simulated using MATLAB simulink environment. The simulation results are presented to verify the performance of the proposed multilevel dynamic voltage restorer. ER -
