This paper is proposed Single phase Multi-Leve AC-DC Converter. This is consist of diode biode and switches The number of the supply current levels depends on the number of the individual converter's current level. In this converter circuit the number of the levels is equal to 2^(M+1)-1, where in is the number of Switching-Leg's number. In this paper is introduced converter with 31 current Level If the number of current level is increased, smoother sinusoidal waveform can be obtained The feasibility of the Circuit is verified by computer simulation using PSIM
