   Influence of Different Pulse-Width Modulation Methods on Magnet Losses in Permanent Magnet Synchronous Machines
By Narciso MARMOLEJO [View]
[Download]

Abstract: This paper compares the effects of different PWM methods and different switching frequencies on the eddy current loss in the magnets of a dual three-phase PMSM. Results of the 3D-FEM simulation display a significant difference in eddy current loss caused by different PWM methods for high-torque and high-speed operating points under the continuous torque boundary.

   Performance Comparison Between SiC and Si Inverter Modules in an Electrical Variable Transmission Application
By Mauricio DALLA VECCHIA [View]
[Download]

Abstract: This paper evaluates the performance of Silicon Carbide MOSFET and Silicon IGBT modules in a three-phase inverter for Electrical Variable Transmission systems. For this purpose, two practical inverter set-ups were developed and compared. An increase of several percentage points is visible over the entire operating range for the Silicon Carbide prototype. The total energy efficiency increased by 3.7\% for the rotor and by 11.2\% for the stator, for the same test conditions.

   Rotor Position Estimation with Hall-Effect Sensors in Bearingless Drives
By Patricio PERALTA [View]
[Download]

Abstract: The estimation of rotor position is fundamental for the commissioning of magnetically-levitated drives. The sensors required for this measurement must be close to the rotor, often requiring constructive mea- sures that may limit the application potential of a drive. This publication presents the estimation of rotor angle and position, based on Hall-effect sensors installed on a slotless bearingless drive. This scheme enables sensor mounting away from the rotor, thus simplifying its encapsulation.

   Variable Switching Point Parallel Predictive Current Control (VSP3CC) for Induction Motor
By Qing CHEN [View]
[Download]

Abstract: This paper presents a variable switching point parallel predictive current control (VSP3CC) strategy foran induction motor. VSP3CC is introduced as one method of the Finite-Set Model Predictive Control(FS-MPC) methodology. VSP3CC implements parallel predictive current control (PPCC) algorithm bymeans of a variable switching point. In this way, not only can a switching state be applied for less than awhole sample cycle which results in a lower current ripple, but weighting factor can also be eliminated.Experimental results are provided to verify the performance of VSP3CC strategy.
