Definitions

  • Kitao a and Watanabe disclose an elevator control system connected to a source of three-phase alternating current which is rectified by a converter to direct current which is converted to a variable- voltage variable-frequency A.C. voltage which, in turn, drives the elevator hoist motor.
  • the present invention provides a motor control system in which power regenerated during braking is dissipated or conserved by altering the composition of the drive waveform. This approach to does not require additional switches beyond those of the inverter output stage to control the flow of regenerated power through the resistor, as is the case with prior art systems .
  • the invention is an apparatus for dissipating regenerated power generated from an induction motor having more than three phases, and comprises an inverter providing more than three different phases of an alternating current output drive waveform, a regenerated power sink, a controller for altering the harmonic content of the output drive waveform provided by the inverter, and a detector for detecting regenerated power when the motor is used as a brake.
  • the resistor array has the same number of phases as the motor
  • the present invention also envisages a resistor array that has fewer phases than the motor, but which may still be activated in the manner disclosed above
  • the resistor array is a three phase array, and is connected in a delta configuration, then the angle between the phases is still 0/360 degrees when driven by third harmonic

Abstract

La présente invention concerne plusieurs dispositifs polyphasés connectés ensemble: un convertisseur (420), une machine tournante électrique (440), et une charge résistive ou résistance de freinage (430). Le rôle de la charge résistive est de dissiper la puissance électrique en excès pouvant être générée lorsque le convertisseur est activé pour ralentir la machine tournante (440), la machine tournante servant en conséquence de générateur. En général, cette charge résistive est une résistance c.c. unique couplée à la liaison c.c. du convertisseur par l'intermédiaire d'un transistor de commande de résistance séparé. Dans la présente invention, la charge résistive est constituée d'un réseau de résistances connectées en polygone, et électriquement connectée aux mêmes terminaux de sortie du convertisseur que la machine tournante. Lorsque l'on souhaite que les résistances absorbent l'énergie, par exemple d'une opération de freinage, le contenu harmonique de la sortie du convertisseur est ajusté, produisant ainsi des différences de tension dans le réseau de résistances (430) et provoquant la circulation du courant dans les résistances.
