| Abstract |
For reduction of the switching power losses
developer of three-phase inverters thinks increasingly about
discontinuous modulation strategies. This applies in
particular for high power inverters such as for starter
generator - or hybrid drive systems. The dc-link current of
these discontinuous modulated voltage source inverter are
analyzed in this paper. First the dc- and the rms-current of
the dc-link circuit are calculated depending on the phase
shift angle and the modulation factor. Afterwards the
current harmonics of the dc-link circuit for a defined phase
shift angle and modulation factor are determined. The
calculations are verified by several circuit simulations. |
