General Modulation Strategy for Seven-Phase Inverters With Independent Control of Multiple Voltage Space Vectors

Drazen Dujic

This paper focuses on the analysis of a seven-phase voltage-source inverter for high-performance motor drives. The problem of the modulation strategy of the inverter is solved by combining the multiple space vector representation with traditional carrier-b ...

A performance comparison of PWM techniques for five-leg VSIs supplying two-motor drives

Drazen Dujic

Component minimized multi-machine drives have recently become an area of much research interest. One such drive comprises two three-phase induction motors supplied by a five-leg voltage source inverter (VSI). With only five legs available to supply two thr ...

Power Supply of Long stator Linear Motors – Application to Multi Mobile System

Yves Perriard, Jean-Jacques Simond, Basile Kawkabani

In large cities, due to expensive land price, high-rise buildings are built, in which the space dedicated to the elevators is considerable and reduces the rented surfaces. To decrease these lost surfaces, a multi mobile system is proposed. It consists of s ...

Current control issues in rotor flux oriented multiphase induction motor drives

Drazen Dujic

Rotor flux oriented control of multiphase induction machines with sinusoidal MMF distribution can theoretically be realized by using only two current controllers in the synchronous reference frame. In practice however this is inadequate, as shown in the pa ...

Experimental performance evaluation of a five-phase parallel-connected two-motor drive

Drazen Dujic

The paper reports the results of an experimental investigation of a five-phase two-motor drive system, consisting of a parallel connection of two induction machines (IM). Thanks to an appropriate connection of the motors, two machines are controlled indepe ...

Modeling and Optimisation of a Hybrid Stepping Motor

Grégory Savioz

The aim of this project is to model and optimise a hybrid stepping motor that drives a closed-circuit television (CCTV) dome camera mechanism. It starts with an implementation of the geometry in ProEngineer (CAD). Then, with the aid of readings and 2D fini ...

Torque Measurement Methods for Very High Speed Synchronous Motors

Yves Perriard, Pierre-Daniel Pfister

The article presents two different torque measurement methods for very high speed synchronous motors: one uses an eddy current brake, and the other is an inertial method. The article also presents a ball bearings friction torque measurement method designed ...

Double trouble

Jean-Jacques Simond, André Hodder, Alexander Schwery

This article presents the modeling, simulation, and practical application of a double-fed asynchronous motor-generator for pumped-storage plants equipped with a three-level VSI cascade. The problem of DC unbalance control is studied in this particular appl ...

A Five-Phase Two-Motor Centre-Driven Winder with Series-Connected Motors

Drazen Dujic

Application of power electronics in variable speed electric drives enables utilization of ac machines with a phase number higher than three. It then becomes possible to use the additional degrees of freedom, available in multi-phase systems, to control oth ...
