Abstract— The conventional methods of ac to variable voltage and frequency conversion such as ac voltage controller and Cycloconverter will gives the more harmonics and low input power factor. And also single phase ac to three phase variable ac conversion also very difficult. The above problems can be overcome by the proposed method in this project, i.e., single phase to three phase conversion with the two parallel connected rectifiers. With this method of conversion the input power factor will be improved. The Proposed Model consists of two parallel single-phase rectifiers, a three-phase inverter, and an induction motor. The proposed topology permits to reduce the rectifier switch currents, the harmonic distortion at the input converter side, and presents improvements on the fault tolerance characteristics. Even with the increase in the number of switches, the total energy loss of the proposed system may be lower than that of a conventional one. The model of the system is derived, and it is shown that the reduction of circulating current is an important objective in the system design. A suitable control strategy, including the Pulse Width Modulation technique (PWM), is developed.
