Multilevel converters are very interesting alternative for medium and high power applications. Multilevel inverter performs is highly superior when compare to two level inverters because of to reduce harmonic distortion, lower electromagnetic interference and high dc link voltages. Somewhat disadvantages are increases number of components and complex pulse width modulation control method and voltage balancing problem. In this paper a new simplified multilevel inverter topology for generation of seven level of output voltage with less number of switches and good voltage balancing presented and multilevel PWM control scheme used to have a minimum power losses and in this scheme three reference signal and one carrier signal used for generation of gate pulses. Simulation results are presented showing the validity of the analysis.
