POWER CHARACTERISTIC COMPARISONS OF AC TRACTION INVERTER SYSTEMS

For traction applications the advantage of improved reliability, reduced maintenance and increased power density are offered by the three phase asynchronous motor. Although use of ac traction motor systems is increasing, development has been slow because of the complexity of the drive system and the lack of comparative data from which system characteristics can be predicted. This paper presents results of an experimental evaluation directed toward accumulating the technical information and assessing the trade-offs which must be considered in selecting an inverter for traction system development. Three inverter systems, (sine wave, pulse width modulated and constant current) were selected as being representative of types available for traction use and were evaluated under similar operating conditions with asynchronous ac motors. Power characteristics, distortion, regeneration, device utilization and their effects on system characteristics and their influence on system selection have been considered and are discussed.
