Dual five-phase power supply system using a three to ten-phase transformer connection

This paper proposes technique to obtain ten-phase output from three-phase input supply system using special and novel transformer connection. With the proposed supply system, pure ten-phase sine-wave voltage/current is obtained that can be used for the motor testing purposes and obtaining dual five-phase supply. The proposed transformer connection yield ten-phase output while the input is grid supplied three phases. Another application area of such transformer can be ten-phase power transmission and rectifier system. In this work an open ended five-phase induction motor is run on the sinusoidal output of a three-to-ten-phase converting transformer. Also two five-phase induction motors with single sided connection are supplied from the proposed transformer connection. Analytical results are validated using simulation and finally by experimental approach.
