Abstract
In present scenario renewable energy sources are crucial and they taking lead to supply power to the consumers. These renewable energy sources mostly generate dc power, which are to be converted into alternating supply for consumer’s use. So there is an impelling need of inverter to convert direct current supply into alternating supply. These inverters are classified into numerous types and depending upon application, the type of inverter is used. In general, a normal inverter will produce square wave output where as a multi-level Inverter will produce staircase waveform which is nearer to sinusoidal. By the level upgrading, the output waveform is very near to the pure sine nature. In this paper, a comparative analysis between the basic Sine PWM and advanced Third Harmonic Injection method for a three level Neutral Point Clamped Inverter (NPC).
