Abstract :
This paper presents the development of a novel waveform synthesis technique for effective voltage sag compensation for multilevel inverter based dynamic voltage restorer (DVR). An effective control algorithm for calculation of reference compensating voltages based on PQR power theory together with space vector modulation (SVM) technique is implemented using a three-level diode clamped voltage source inverter(VSI) configuration. Extensive simulations are carried out under various test conditions and the results show that the proposed scheme for voltage sag compensation is seamless with negligible THD
