| Abstract |
A five-phase two-motor drive system with series
connection of stator windings and decoupled dynamic
control has been introduced recently. The two-motor drive
system is supplied from a single five-phase voltage source
inverter (VSI) and controlled using vector control scheme. If
current control is to be implemented in the rotating
reference frame, a PWM method for the five-phase VSI is
required to generate required voltages. This paper proposes
a scheme to generate inverter output voltages using space
vector PWM, in such a way that independent control of two
five-phase series-connected machines is achieved with a
minimum interaction between the two machines. The
method generates output voltages that contain only two lowfrequency
fundamentals at operating frequencies required
by the two machines. The concept is verified by simulation. |
