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.

Keywords

We observed that results are verified with Matlab Simulink.
