Abstract synthesis of dc-to-dc converter topologies in the two largest families - pwm and quasi-resonant (qr) - is completed in this thesis in a pwm converter, two linear time-invariant networks, consisting of only capacitors and inductors, source and load, are switched at constant frequency with duty ratio d. Synopsis of the thesis certain investigations on vsi fed induction motor drives source inverter used different pwm control techniques this paper finds output current 13 objectives and organisation of the thesis the objectives of the present work are as follows. Pwm (pulse width modulation) is a technique by which we simply control the digital output signal by switching it on and off very quickly, by varying the width of the on/off duration, it will give the effect of varying the output voltage.
