Abstract:

 In this paper we proposed novel method was introduced for driving 2 Independent three phase induction motors by feeding through four- leg inveter(FLI) which can have capability of driving three phase AC motos also. It basically consists of four legs two capacitors connected in series and similarly U and V phases of both motors are connected to each leg on the other hand W phase of both motors is connected over to neutral point of two spirit capacitors.For the sake of modulation to phases only PWM method os not directly applied here.
