hai all,i am doing 3 phase ac motor drive.Now i have a problem that the input voltage for drive is 440-volt AC and it should be rectify to dc and after removing the ripples the voltage should be increased and i have to give the voltage to igbt's emitter and the output for igbt is nearly 650volt.I heard that the input of the motor should get 440volt only.Guy's can you please give me some information for rectifying this problem.
