“…The most promising advantage of a five-phase induction motor drive is the ability to provide torque with one or two non-adjacent phases [2][3][26][27][28][29][30]. This advantage is paid with a current increase of the remaining healthy phases.…”

The paper presents a sensorless control approach for a five-phase induction motor drive with third harmonic injection and inverter output filter. In the case of the third harmonic injection being utilised in the control, the physical machine has to be divided into two virtual machines that are controlled separately and independently. The control system structure is presented in conjunction with speed and rotor flux observers that are required for a speed sensorless implementation of the drive. The last section is dedicated to experimental results of the drive system in sensorless operation, and the uninterrupted drive operation for two open-phase faults.

“…In order to obtain a maximum allowable dc-link voltage, each switch in the upper group must be turned on when the corresponding input phase voltage is the highest input-voltage at the instant considered [28]. In contrary, each switch in the lower group must be turned on if the corresponding input phase voltage is the lowest input voltage at the instant considered.…”

This paper proposes a simple carrierbased PWM (CBPWM) technique to control the threeto five-phase Direct Matrix Converter (3×5 DMC). The proposed technique uses the indirect modulation approach to control the 3×5 DMC such as a threephase bidirectional rectifier followed by five-phase voltage source inverter (VSI). Based on this approach, it is possible to synthesize the desired five-phase output voltages with sinusoidal three-phase input currents and unity input power factor. A CBPWM method is suggested for each stage independently including both linear and overmodulation operating modes. By the proposed technique, in both operating modes, the maximum possible overall Voltage Transfer Ratio (VTR) is achieved. Moreover, this technique allows the input power factor to be controlled by controlling the input current displacement angle. The feasibility of the proposed technique has been verified by a series of simulation and experimental results based on Matlab/Simulink and dSPACE-DS1104 platform. The results show that a sinusoidal output and input waveforms can be achieved with a maximum possible VTR in the linear region. However, in the overmodulation region, a maximum possible VTR is achieved at the cost of some distortion of output and input waveforms. Therefore, this technique can be used for the application where a higher VTR is essential.

“…It is noted that the similarity between two approaches ,in multilevel inverter the additional switching devices increase the number of voltage levels, while in the multi leg inverter, the additional number of switching devices increases the number of phases. The performance under faulty conditions in voltage source inverter or in motor windings is one of advantages of multi phase motor [7]- [10]. Two techniques are used in five phase inverter, one, is the carrier based pulse width modulation (PWM) and the other is the space vector modulation (SVM) [11]- [14].…”

This paper proposes new topology of five-phase inverter with reduced number of switches fed indirect rotor field oriented five phase induction motor. It employs only eight IGBT switches preformed five phase inverter. The reduction of the number of power switches from ten to eight improves the cost-effectiveness, volume-compactness and reliability of five-phase induction motor drive system. Simulation model of the proposed drive system is developed using the Matlab/Simulink package and analyzed to verify the effectiveness at different operating conditions of this approach. The comparison between the performance of the five phase motor under classical ten switch inverter and new topology at the same operation conditions has been illustrated. The proposed system gives similar operations as classical ten switch inverter for a certain range of motor speed and load torque. The DC voltage of proposed inverter must be compensated to higher value to achieve same performance of classical ten switch inverter in all range of motor speed and load torque.
