Abstract
This paper presents a five-phase induction motor drive
system fed from a three-to-five-phase matrix converter. This
is a new concept of generating variable voltage and variable
frequency five-phase output using a special matrix converter.
This matrix converter is proposed recently which transform
the available three-phase supply to five-phase supply. Simple
carrier-based PWM scheme with enhanced approach is
employed to control the output of the matrix converter.
Enhanced approach is utilized so as to increase the output
voltage magnitude of the three-to-five-phase matrix converter.
The motor is controlled in constant v/f mode. Simulation study
is carried out for excitation, acceleration, loadingand reversing
transients. High quality dynamics are observed.
