A multilevel H-bridge dc–ac converter is an electronic device, the multilevel converter enhanced stepped output with less switches. This paper deals with H-Bridge multilevel converter it requires only few switches when compared to traditional method. So in proposed method using only few switches, and it requires less gate triggering circuit. Less switches will operates for certain period of time. The proposed circuit is simulated using MATLAB software in that fast Fourier transform test to find the total harmonic distortion. With the proposed method multilevel converter can be used in solar power applications to convert dc supply into ac supply, it produces less harmonics it will enhance life span of the motor and efficiency of the motor will raise because in proposed multilevel converter there is a less switches are used.
