This-effort displays an idea to straightforwardly mitigate sag in PV-Inverter system. ‘This effort deals with designing, modeling &comparison of PV fed Bootstrap converter and three phase inverter (PVBSCTPI) system with and without LVRT (Low voltage ride through). Here, PV is utilized as a source.„_The-Simulink-models for-PVBSCTPI with and without LVRT have been-developed using the-elements of Simulink&-investigations are executed. The outcomes are compared-in terms-of output voltage, Real & Reactive power. The outcomes represent that voltage sag of PVBSCTPI system is mitigated using a DVR. The improved performance-in terms-of voltage has been obtained with LVRT based - PVBSCTPI system. The output voltage and power are found to be higher with LVRT.
