Abstract

This paper presents a novel seven-phase open-end winding drive system supplied by the dual non-square matrix converter. The input to each of the matrix converter is three phase utility grid system and the output is seven phase voltages with variable voltage and frequency. The two matrix converters feeding a seven-phase load are supplied from a common single three-phase utility source of 50 Hz. Space vector based PWM algorithm is developed to control the dual three to seven-phase matrix converter. The proposed control technique eliminates the common-mode voltage across the machine winding and hence no zero sequence currents will be produced and therefore no isolated supply is required for the dual three-to-seven phase matrix converter system. Further the proposed technique will enhance the seven phase machine phase voltage to 1.95 times the voltage produced by a single three to seven phase matrix converter system in the linear modulation range. The paper presents the analytical approach to obtain the expression of modulating signals that are used to generate the switching pulses for the matrix converter. Simulation results are presented to support the idea of the proposed modulation scheme.
