There is rapid development in the power system applications in early from the 19 century in many areas like transmission, distribution and power system appliances. In the year 1970 there is rapid development in the sector of machines. In late 1970 the first five phase induction motor drive system was proposed the world. Since there is huge research attempts has been placed to develop the multiphase drive systems. The three-phase supply is available from the grid; there is a need to develop a static phase transformation system to obtain a multiphase supply from the available three phase supply. So this paper suggests a novel transformer connection idea to convert the three phase grid supply to a five phase fixed voltage by maintaining the constant frequency supply. Now days the use of five phase motor dive is ever-increasing in commercial purpose and in future also. To satisfy these there are having solutions first, implementation of six phase transmission. To implement this we have ...

Multiphase (˃3Ø) systems are greatly under research recently due to their inherent advantages compared to their three-phase (3Ø) counterparts. The Multiphase system applicability is explored in electric power generation, transmission, and utilization. The first multiphase motor drive proposal was given by Ward and Harrer way back in 1969.The grid supply is available as three phase supply, hence there is a static phase transformation system required to obtain a multiphase supply from the available three-phase supply. Multiphase Inverters and Special Transformer connection Technique are two methods used to convert Three-phase supply to Five-phase supply. In this paper three to five phase transformation using special multi-winding transformer connection scheme is presented. Three single phase Multiwinding transformers are designed, two transformers having one primary and three secondary windings and the third transformer has one primary and two secondary windings. The proposed transformer connection has three phase input and outputs five phases to transform balanced fixed voltage-fixed frequency three phase power into balanced fixed voltage-fixed frequency five phase power at its output. The special connection scheme of multi-winding transformers is simulated by using "SIMPOWERSYSTEMS" block sets of MATLAB/SIMULINK software.

A Multi Phase Transformation System Using a Special Transformer Connection
this paper proposes a novel transformer connection scheme to convert the three phase grid supply to a five-phase fixed voltage and fixed frequency supply. The output transformer connection outputs five phases can be used in applications requiring a five-phase supply. Multi-phase motor drives have been studied from more than thirty years. The interest has grown so that some international power electronic conferences have hosted sessions on the multi-phase motor drives. Generally, multi-phase machines drive has many advantages over conventional three-phase drive such as high power handling capability by dividing the required power between multiple phases, reduced torque pulsations and higher reliability. Three phase drive, the loss of stator phase does not prevent the machine from starting and running. The main advantages of multi-phase systems are reduced rotor harmonic currents, increased torque per ampere for the same volume machine, reduced stator copper losses. The main application areas of multiphase induction motor drives are ship propulsion, traction (including electric and hybrid electric vehicles) and the concept of more-electric aircraft. A difference between Three-Phase supply and Five-Phase supply. Other suitable applications are locomotive traction aerospace and high power applications. Presently the grid power available is only limited to three-phase so the supply to multi-phase motors is invariably given from power electronic converters.
Three Phase to Five Phase Conversion Using 3 Single Phase Transformers
2016
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 'SIMPOWERSYSTEMS' block sets of MATLAB/SIMULINK software.

Transformers are able to step up or step down an output voltage from their input. It also can be used to directly supply an electrical motor when a constant frequency operation is required. Here, the research is focusing on designing a three-to-five phase transformer that acts as static phase converters for supplying a balance five-phase load. The designing process of the transformer is described based on the graphical phasor diagram that is flexible and easy to be implemented. At the end, the performances of the designed transformer are evaluated using a static and dynamic load. The designed three-to-five phase transformer is able to maintain a balance five phase voltage for several type and level of load as shown in experimental result.
