چکیده

The proposed paper deals with steady state estimation of a electromagnetic torque ripples and a current waveform of a two-phase induction motor (IM), which is supplied by an three-leg voltage source IGBT bridge connected inverter (VSI). The complex Fourier series analysis of the inverter’s output voltage was made, to obtain an analytical formula of supply voltage waveform. The space phasor theory has been applied to the two-phase induction machine model to obtain electromagnetic torque and supply current waveforms for various operation states.

The Vector Control of Three-Phase Salient Pole Synchronous Machines Supplied by Pulse-Width- Modulated Voltage Source Inverters

In this paper, computer simulation of a three-phase synchronous motor drive is described. This drive/system is supplied with a new type of pulse-width modulated voltage source inverter (PWM VSI) whose amplitude of the first harmonic, compared to a conventional sinusoidal PWM VSI, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their or...

Fuzzy Logic Control Based Direct Torque Control Scheme for a Four Switch Inverter-fed Induction Motor Drive

Direct Torque Control of induction motor fed drives has become popular and widely used in industries due to fast and good torque response. Induction motors (IM) are simple in construction and are less sensitive to the motor parameters compared to other vector control methods. A new torque and flux control scheme called the direct torque control (DTC) has been introduced for induction motors. In...

Fault Tolerant Multiphase Electrical Drives: The Impact of Design

This paper deals with fault tolerant multiphase electrical drives. The quality of the torque of vector-controlled Permanent Magnet (PM) Synchronous Machine supplied by a multi-leg Voltage Source Inverter (VSI) is examined in normal operation and when one or two phases are open-circuited. It is then deduced that a seven-phase machine is a good compromise allowing high torque-to-volume density an...
