Abstract in another language

Some fault-tolerant three-phase inverters are based upon a reconfiguration to an inverter with only two
active phases and a DC-link midpoint connection after any semiconductor failure. Thus, the maximum
output voltage is halved and the DC-link midpoint capacitor voltage ripple depends on output frequency
and output current of the inverter. These limiting effects on the operation range of adjustable speed drives
as well as software and hardware based countermeasures are presented in this paper.
