19-55 UTILIZAREA INDUSTRIALĂ A CONVERTOARELOR STATICE DE MARE PUTERE (II)


INDUSTRY APPLICATIONS WITH HIGH POWER STATIC
CONVERTERS
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.
However, this article presents a real application in Kronospan S.A.
Sebes, with an ACS 5000 ABB static frequencies converter.
Keywords: power electronics, inverters, two and three levels of voltage,
direct torque control, industrial applications
Cuvinte cheie: dispozitive electronice de putere, invertoare pe două şi
trei nivele de tensiune, control direct de cuplu, aplicaţii industriale
