Abstract
This paper explains the PV combined Z-source inverter (ZSI) based Dynamic Voltage Restorer (DVR) for power quality improvement. In order to generate reference voltage for DVR, SRF technique is used. For gate pulse generation Adaptive HCC, fuzzy logic are used to examine the control of DVR under un balanced supply condition. For creating un balanced supply a three phase programmable voltage source is taken. This voltage is compared with reference voltage generated by SRF technique. The charging control scheme of the DC-link bus integrated PV cell requires DC/DC converter it is eliminated by using ZSI which makes boost & buck operation. The MPPT technique used in PV system is the combined algorithms of P&O, INC. This combined algorithm is very useful for any kind of parameter variation and it provides better efficiency. The ZSI base DVR is computed and validated and designed through Matlab/ Simulink model.
