Combinational-Logic-Based Traction Inverter Fault Diagnosis
IEEE Transactions on Industry Applications, 2015This paper presents a combinational-logic-based approach for identifying faults that could occur in power electronic components of an electric vehicle inverter. A real-time simulation model of an electric vehicle is used to study the behavior of available sensor signals and control commands, with specific measured quantities, during vehicle operation ...

Inverter-Fed Asynchronous Motors for Traction Systems
IFAC Proceedings Volumes, 1977Publisher Summary Variable-frequency inverter-fed asynchronous motor constitutes, in the field of electric traction, an effective option to traditional d.c. motor. The success of this equipment is connected to the advantages the squirrel cage asynchronous motor may provide lower weight and small dimensions, higher power at high speed, less ...

GTO Inverter for AC Traction Drives
IEEE Transactions on Industry Applications, 1983A 600-kVA capacity GTO inverter for traction drives has been developed using 2500-V/1000-A gate turn-off (GTO) thyristors, and running tests have been carried out. To utilize the advantages of GTO thyristors, circuit inductance of both main loops and snubber loops were minimized in order to decrease overvoltage applied to GTO thyristors after turn-off.

Cascaded multilevel inverter for underground traction drives
2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012The elementary concept of a multilevel converter to achieve medium and high voltage by using a series of power semiconductor switches with several lower voltage DC sources. A suitable modulation technique is required to perform the power conversion by synthesizing a staircase voltage waveform to reduce the Total Harmonic Distortion (THD) of the multi ...

An Inverter for Traction Applications
IEEE Transactions on Industry Applications, 1972An inverter configuration with an auxiliary shutoff circuit designed for traction applications is described. The auxiliary shutoff energy adds to the main shutoff energy providing the necessary shutoff capability at stall and low motor speeds where maximum traction is required.

Smart inverter drive for traction
1998 International Conference on Power Electronic Drives and Energy Systems for Industrial Growth, 1998. Proceedings., 2005Two advantages of having electric drives in road vehicles are that there is a reduction in the number of mechanical parts and an increase in environmentally-friendly operating conditions. In addition, electric vehicles are not only used for engine-driven acceleration but also for generator-driven deceleration which thus achieves a high degree of total ...
