报告摘要：The single-phase input three-phase output converter-fed induction motor (IM) drive has been found widespread applications in residential and some industrial areas. In order to ensure that the converter drive system can continue to operate in the event of a fault, a fault-tolerant topology of induction motor drive system is presented. In addition, a well-known problem with the single-phase ac network is that the instantaneous power flowing from the ac-side is time-varying with twice the grid frequency. If the ripple power is not properly filtered, it will spread to the device on the dc bus and further influence motor’s performance. Finally, to make a trade-off between cost, reliability, and control performance, this talk presents a fault-tolerant induction motor (IM) drive system with power decoupling capability. Considering the strong coupling of all kind of components in the system, a hybrid model predictive control (MPC) is introduced to coordinate the operation of the decoupling circuit, rectifier, and inverter circuits.
