Like many steel mills throughout the world, a recent TMEIC customer in Tuscaloosa was searching for a solution to increase production at its facility. An aging steel rolling Steckel mill, powered by large DC motors and controlled by variable speed DC drives was limiting the full production potential of the mill.
The use of power diodes and Thyristors in applications such as small and large appliances, such as UPS systems, AC/DC rectifiers, and variable speed motor drives is the primary source of harmonic distortion in AC grid or mains current. Due to the source impedance of the mains power, the harmonic load current
