Run-Time Reconfiguration of Tandem Inverter for Induction Motor Drives

The paper presents a short introduction to reconfigurable systems and why are they used or should be used in control of AC drives. The reconfigurable vector control system is introduced and there are treated the reconfiguration problems. There is analyzed the reconfigurable control system and it is motivated the need for reconfiguration in motor control. The control of the induction motor fed by the tandem inverter needs reconfiguration if the supply is made only from one inverter instead of the both component ones. Finally a simulation and fast prototyping method is shown using Field Programmable Gate Arrays.
