English abstract:
Recent developments showed that existing passive three-phase
rectifier circuits with DC-side located smoothing inductor can be
extended to a low harmonic input stage by adding an additional
converter stage on the DC-side of the passive rectifier system. In
this paper an implementation of this converter stage using reduced
number of semiconductors (only two half-bridges) is proposed. The
system shows input current distortions which can be reduced
considerably to values below 1% if switching frequencies of 72kHz or
above are used. A proper design of the injection chokes is thereto
required and several operating modes and optimization possibilities
are discussed. Design guidelines are verified by simulation results
and a laboratory prototype based on a 10kW/72kHz rectifier system
using SiC-MOSFETs.
