| Abstract |
The power factor and the waveforms of the currents of voltage source inverters can be improved essentially when two pulse inverters are used - one at the lineside and the other at the machine-side. Both inverters are controlled by similar current vector controllers. The reference value of the stator current can be calculated by field-oriented control or by decoupling (1), (2) for example. The reference value of the line current is derived from the actual state of the mains and the machine. Furthermore on-line optimization of the pulse pattern by PROMC is used. |
