The locomotive control system performs all of the traction power control and dynamic braking in diesel –electric locomotives with up to six axles powered by AC induction motors. The operating voltage of up to 1100V DC allows the use of  typical prime movers and generators of  existing and legacy designs with minimal change. Individual control of the currents on each AC induction motor by IGBT inverters provides the benefits of excellent traction control, wheel spin and slide correction, and smooth dynamic brake control at all speeds. These benefits have particular value for maximizing the train weight that can be handled by low –speed switching and general-purpose locomotives. Consult Saminco for additional options.
