ATS designs and manufactures high efficiency propulsion systems and accessories for new or remanufactured light rail vehicles using AC or DC traction motors. Our power conversion equipment is based upon a set of compact liquid cooled IGBT modules operating from a common DC bus. Modules are designed to fit the entire propulsion system into extremely tight quarters. Modules are sold individually, or an entire system can be mounted and wired on racks or in lockers at our factory.
