| Abstract |
A 3-phase pulsewidth-modulated reactive-power compensator is presented. It is a topology that resembles a Current Source Inverter (CSI) that is shorted on the DC-side. The converter is operated at a high switching frequency which renders the potential to generate nearly undistorted current waveforms. In comparison with traditional compensators the energy storage elements can be relatively small, depending on the switching frequency. By application of an appropriate switching scheme, the reactive power is almost instantaneously transferred from one port to another port of the 3-phase system without substantial energy storage. Test results are shown of a compensator-model which is equipped with IGBT's and which switches at 20kHz. |
