Multilevel inverters are a good choice for medium and low power applications. Multilevel inverters have found a wide place in the market for their good power quality output. This paper proposes a new Envelope with T type Novel Multilevel inverter with unequal sources and with reduced switch count. Working of the circuit is explained. Firing angle calculations are done using simple nested looping technique and later Genetic Algorithm is used to obtain optimum firing angles for Selective Harmonic Elimination technique and improve the THD of the output voltage. Comparison is made between different types of inverters. The proposed inverter can be used for speed control of drives
