Finite Set Model Predictive Current Control with Reduced and Constant Common Mode Voltage for a Five-phase Voltage Source Inverter Conference Paper uri icon

abstract

  • Multiphase drives are now becoming serious competitor to traditional three-phase drives due to reasons of better fault tolerant property and reduced per-phase converter rating that are especially suited to high power drives application. One of the major factor of widespread research on multiphase drive are the availability of high computational power of control platforms such as DSP and FPGAs. With availability of such computationally powerful tool of DSP/FPGA leads to the adoption of model predictive control (MPC) in electric drive. This paper present current control of a five-phase inverter using MPC with the aim of achieving constant common mode voltage. By achieving constant common mode voltage (CMV), bearing current can be greatly reduced. This is achieved by proper selection of space vectors and analysis of drop in voltage gain is presented. Simulation results are supported by experimental approach. © 2014 IEEE.
