Abstract :
Some problems and their solutions of vector control systems of medium voltage three-level inverters are introduced in this paper: Inverter output voltage and current measurements, counting the influence of output filter on vector control, compensating the delay of the current differential signals in calculating motor EMF, new motor voltage model, the current precontrol and compensation method of motor parameter variation. All the solution can be used for both induction and synchronous motor control systems.
