Present and Future of Fault Tolerant Drives Applied to Transport Applications

摘要: An electric drive is an electromechanical conversion device, consisting of electrical machine, a power electronic inverter, which interfaces between the machine and supply, set sensors digital controller. Drives this sort are manufactured in high volumes at levels ranging from less than 1W to many MW. Reliability complete system depends upon local environment, thermal cycling predictive maintenance schedules. Overall has typical reliability order 10-5 failures per hour, making it much more reliable than, say, internal combustion engine. As part “electrical revolution” drives increasingly being developed for safety critical applications, where their several orders magnitude below application requirements. This particularly case propulsion actuation systems aircraft, leading intensive research into fault tolerant drives. paper will illustrate some most common failure mechanisms consequences such failures. It then progress examine architectures through partitioning independent lanes penalties adopting approach. The discuss pros cons different suggests future development steps that required increase overall
