Multilevel Inverters have emerged in power conversion systems due to their lower output harmonics and high power capability. This paper presents the performance analysis of a new seven level symmetrical multilevel inverter with reduced number of switches using Carrier Overlapping PWM strategies. Due to switch combination redundancies, there are certain degrees of freedom to generate multilevel AC output. The results are compared with sine and Trapezoidal references in Carrier overlapping technique. Harmonic analysis and performance measures for various modulation indices have been carried out.
