The use of resonant converter principle in variablespeed AC drives is presented. This paper achieved by pulse-withed modulation of the inverter switches. But conventional PWM inverter is employed hard switching by means a switching device. Moreover this paper presents resonant DC link voltage type inverter that it was not necessary snubber circuit and dead time and modeling of AC MOTOR drive control system aud simulating analysis are studied.
