Due to the potential benefits resulting from the use of a phase order higher than three in
transmission, some interest has also grown in the area of multi-phase machine. For machine …

The developments in the power electronics field have lead to an ever-increasing use of
static switching devices to control the torque and speed of ac motors. Invariably, the output …

The interest in using the matrix converter (MC) for motor drive applications and energy
conversion systems is steadily increasing due to its main advantage of performing a direct …

The effects of different input voltage measurement methods on the stability of a matrix
converter drive system are analysed. In particular, with the aim of improving the maximum …

The stability study of a multi-phase (six-phase) induction machine has been performed by
applying the eigenvalues stability criterion to the small displacement equations obtained by …

The historical development of power electronic converters to control electrical machines is
traced up to the present state of the technology. The fundamental possibilities to control …

Problems of stability of input filters of drives controlled by direct torque and flux control
methods are studied. Two direct methods for AC drive control, Depenbrock's (DSC) and …

Small signal stability analysis is conducted for an asymmetrical six-phase synchronous
motor in comparison with its equivalent three-phase counterpart. For this purpose, a …

This thesis considers robust control of an induction motor drive, consisting of an input filter, a
voltage source inverter and one or several induction motors in parallel. The motor torque is …

In this paper the stability of an electrical drive fed by a three-phase to three-phase matrix
converter is analyzed considering two different control schemes. In the former the duty …
