A Novel Three-Phase to Five-Phase Transformation Using a Special Transformer Connection

Abstract

In today’s electrical scenario due to ever increasing demand of more power it is necessary to supply it at a certain voltage level economically, which restricts it to a certain value. Moreover there are other limitations on utilization side as well. The solution for this is use of multiphase systems. Nowadays multiphase systems are being thought of as a solution for the problem and research in this field is picking up pace. There is a need to obtain multiphase supply from the available three phase supply due to its inherent advantages. PWM Technique is most suitable for employing two-drive systems with variable frequency which is more complicated. Hence Special Transformer Connection method is used in applications requiring fixed voltage and fixed frequency supply. This model can be simulated by using ‘SIM POWERSYSTEMS’ block sets of MATLAB or SIMULINK Software
