Апстракт:
The use of AC Drives in the industry applications has seen tremendous growth over the last 40 years with the rapid development of high-power semiconductors, power converter topology, new control strategies, and their implementation with the advanced digital processors. These have mode it possible to design drives with higher VA rating, with PWM and VC / DTC. The fast ascension of AC electric drives and static power converters was possible through a continuous and fabulous development of the performances of the semiconductor power devices during the last 50 years. The direct control strategy of the torque (DTC) has appeared as a method in 1987, as an alternative to the method of orientation with respect to the field, and it was implemented by ABB in 1997. The characteristics of this method are the easy control of the torque and of the stator flux without utilizing the traditional transformations of axis and vectors d-q, without utilizing the pulse of width modulation (PWM), with no current reaction and with no PI-type regulators. However, this article present a real application in Kronospan S.A. Sebes Romania, where for the first time in Romania a medium voltage static converter was put in function with the load voltage of 6kV.
