Fault-Tolerant Control Research of Vehicle-Mounted 5-Phase Inverters

Abstract

As the electricity conversion switch of electric vehicles, the inverters play an important role in vehicle’s driving and regenerative braking process. Therefore, the research in fault-tolerant control of inverters has important significance. This article applied a 5-phase fault-tolerant inverter into the electric vehicles, and researched its single-phase and double-phase fault-tolerant control. The experiment results prove that the 5-phase fault-tolerant inverter can assure the vehicles run as usual with single-phase or double-phase fault.
