Whenever Three - Phase Induction Motor is in running condition , there is a problem with ripple torque & harmonics. This hampers the smooth operation of the machine and it also aggravates the amount of heat generated. The ripple content can be smoothened by supplying the motor with multi phase supply greater than three phase supply. Selection of even number of phases should be avoided, because it degrades the performance of motor as poles coincide with each other. So, Five Phase Supply /Odd Phas es may be preferred. This paper proposes a difference between Three - Phase supply and Five - Phase supply. Five - Leg Inverter is a converter converts DC to variable AC (i.e., variable voltage and variable frequency). Output of the five leg inverter is controll ed by PWM control technique method . It is highly economical , has more Efficiency and good controllable .
