New 'AC/AC' Propulsion System for the INNOVIAAPM 300

摘要

Bombardier Transportation Divisions, Systems, and Propulsion and Controls, as part of the INNOVIA APM 300 vehicle development, are developing a new propulsion system to drive two AC traction motors from 600VAC, 3 phase track power rather than two DC traction motors as is the applied technology on our legacy APM 100 products (formerly CX-100). The new propulsion technology, consisting of two independent line converter/motor converter pairs, is referred to as the "AC/AC" propulsion system. The resultant INNOVIA APM 300 AC/AC car, offers many improvements to our customers, such as, propulsion redundancy for improved availability, improved performance from better power factor correction methodology, reduced energy consumption from regenerating braking energy back into the mains power source, and a top speed boost to 50mph (80kph) from the 34mph (55kph) maximum previously ever deployed with the APM 100 system. This paper summarizes the key development efforts of the new AC/AC propulsion system, and provides a comparison of features against those of the legacy APM 100.
