Analysis of Newly Developed Third Harmonic Injection Mothod with Ovpmw Method for a PV System Connected Through 3-Level Diode Clamped Inverter to an Induction Motor

摘要

This paper clarifies a relative investigation of tweak strategies for 3 level NPC Voltage Source Inverter for a heap associated Photo Voltaic (PV) framework. The examination is completed on two sorts of adjustment systems utilized as a part of three level MLI, viz. Recently grew third harmonic injection technique and ovpmw adjustment. The motivation behind the review is to dangerously break down and arrange the issues related with existing DCMLI utilized. It is watched that the three level Diode Clamped Multilevel Inverter (DCMLI) experiences limit beat width and does-interface capacitor voltage unbalancing, when associated with the most astounding appraised PV framework. Also, this issue results in wasteful execution of DCMLI, accordingly aggravating the power quality. The examination likewise accentuates the current balance procedures, albeit well known for inverters however neglecting to meet the present prerequisites when associated with MLI. The perception is checked by planning and actualizing the model in MATLAB/Simulink and appropriate outcomes are shown.
