- Description
- This paper presents an approach to completely eliminate common-mode voltage (CMV) of an AC motor fed by a three-level neutral point clamped (NPC) inverter. CMV is produced at the star point of an AC machine fed from the inverter. Its parasitic coupling with the motor frame has a negative effect on the motor itself and other equipment, particularly in underground environment. The proposed approach to eliminate CMV, in combination with capacitor voltage balancing, is based on simplified model predictive control (MPC). Simulation results implemented in MATLAB-Simulink environment confirm that the proposed MPC algorithm successfully removes CMV, which makes it a promising control technique in industrial applications.
