| Abstract |
The paper proposes a new topology for electrical
drives using a reduced matrix converter. Modifying the classical
matrix converter topology that way, that only two output phases
with unidirectional current flow remain, the number of
unidirectional active switches can be reduced to 33%. The
commutation strategy becomes inherent safe and simple
compared to the classical matrix converter. Problems with static
magnetic fields in the stator field of a three-phase machine,
caused by the DC-parts in the two converter output currents,
can be solved using a transformer. A great advantage over
former presented reduced topologies is that the mains currents
are symmetrical to time axis in principle. |
