Fault-tolerant reversible ac motor drive system

IEEE Transactions on Industry Applications, 2002
This paper investigates a fault tolerant three-phase AC/AC converter topology. With such a topology, when either one leg of the input rectifier, or one leg of the output inverter, is lost, the power flow between the grid and the load can still be controlled effectively. The topology proposed and its operating principles are presented.

Predictive Control of Permanent Magnet AC Motor Drives

2005 IEEE Conference on Emerging Technologies and Factory Automation, 2006
A predictive control algorithm for PMAC motor drives is presented in the paper. The proposed approach, implemented in rotor coordinates, allows to impose the reference values of d and q current components using recursive algorithms. The output of the digital control system directly imposes the timing control of the inverter by means of on/off state of ...

Flexible Series/Parallel AC–DC–AC Motor Drive System

IEEE Transactions on Industry Applications, 2015
This paper presents a three-phase ac–dc–ac drive system to cope with applications in which high performance and reliability are required with reduced dc-link and switch blocking voltages. The subsystem at the grid-side can be implemented into two alternatives, i.e., topologies G1 and G2.
