Three Level Neutral Point Clamped Inverter Using Space Vector Modulation with Proportional Resonant Controller

Renewable energy is spreading in various format of supplying electricity such as in domestic purposes, grid integration, power generation and hybrid vehicle. Grid integration is one of the aspect is a necessary concern. This paper elaborates the control strategy installation necessary for grid integration. Most of the time, conventional inverters are used but in this paper the new multilevel inverter control strategy is taken for various purposes including cost, simple construction and less losses. This paper introduces a three level NPC inverter which uses space vector modulation for pulse generation. Three level NPC inverter contributes many benefits such as power quality improvement, reduction in harmonics, lower cost and improved efficiency. This document involves a novel control strategy with voltage oriented control using PR controller which helps the system to cope up the difficulties of the grid transmitting energy.
