Abstract

PURPOSE: A controlling system capable of remarkably reducing the size of acommutation reactor and capacitor, wherein the load current is compared with a predetermined value in starting time of a D.C. motor, a subthyristor is turned on when the former is equal to the latter value,while a main thyristor is turned off before it will reach to apeak load current.
