Automatic close control device and control method for a static converter for powering an electric machine.

摘要

The close-control device is intended to control a static invertor and comprises two identical random-access memories (1, 2) which are placed alternately in read mode or in write mode so as to contain control patterns for the invertor. At each instant control is ensured through the pattern read from the memory in read mode and simultaneously a new pattern can be written to the memory in write mode so as to allow a modification of the operating regime. Permutation instructions ensure permutation of the modes of the two memories. Furthermore, the control device comprises a unit (8) for temporal generation of read addresses and a unit (7) for conditioning signals emanating from sensors, which are associated with a module (6) for selecting addresses, which impart a universal character to the control device enabling it to control the principal types of existing electric machines and in particular self-driven AC machines. <IMAGE>
