An Approach to a 3-pole Active Magnetic Bearing System Fed by a Matrix Converter

This paper presents a MATLAB/Simulink model for a 3-pole radial magnetic bearing system that is fed by a matrix converter (MC). The active magnetic bearings (AMBs) system model that is studied here is shown and tested in [1] using a simplified inverter model, so that the main contribution of this paper lies in the simulation, study and analysis of the AMBs performance under a MC supply. In order to achieve this objective, a more complex inverter model, including the rectifier stage, and a MC model are implemented, analysed and compared in conjunction with the bearings. Results from models described in [1] are taking into consideration in order to verify the new models performance.
