By combining the field-weakening control principle of a new axial flux-switching permanent-magnet motor (AFFSSPM) with the space vector pulse width modulation (SVPWM) and maximum torque per voltage (MTPV) control principle, a novel field-weakening control strategy for AFFSSPM is proposed in this paper. In the first stage of the field-weakening, the difference between the reference voltage updat...

This article presents an enhanced space vector pulse width modulation (SVPWM) strategy based on decomposition (VSD) for the dual three-phase machines fed by two dc-source voltage source inverters (VSIs). Compared with existing methods that only account balanced dc-link voltages, proposed method considers unbalanced voltages in both α-β and z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" x...

This paper presents Load Current Control based on Luenberger Observer for Three-Phase Power Converter SVPWM with current regulation. The use of observer is intended to replace the use of dc current sensor, so it eliminates the nonlinearity problem and drop voltage caused the sensor. This research develops a controller to improve the time response of the dc output voltage of the three-phase powe...

This paper presents the application of Space Vector Pulse Width Modulation (SVPWM) technique to reduce torque ripple in an induction motor employing Direct Torque Control (DTC). The effective time is determined using imaginary time vector there by the lengthy procedure of using reference voltage vector is eliminated. Also the sector identification and angle determination are not used. Simulatio...

Over the past few years, there has been an increase in use of open-end winding (OEW) PMSM applications. The fault tolerance topology makes OEW suitable for various intermittent operations. However, a dual inverter operation causes drive schemes to exhibit high commutation and ripple. This paper presents optimized alternative fixed switching 12-sector space vector pulse width modulation (svpwm) ...

Pulse Width Modulation (PWM) driven power converters are widely used in realizing the function of rectification and inversion renewable emerging applications. They play a key role tying energy sources solar wind to conventional grid systems. Such emergying styles systems referred as Distributed Generation (DG) or mix. The PWM-based switching devices also for injecting harmonics degrade quality ...
