Fig. 10 shows one phase of a three-phase
converter for a power of about 80 kW.
The useful output power naturally depends
on the dc-link voltage and the switching
frequency of the converter. The IHD680
allowed the converter to be operated with
frequencies up to far above 20 kHz in
principle, although at these frequencies
considerable switching losses occur in the
IGBTs and the output power must be
correspondingly
power of the IHD680 is also sufficient for
a parallel circuit comprising several
modules of this type. For switching
frequencies below 10 kHz, one IHD280 is
sufficient for this IGBT module.
The complete three-phase converter is
available in the circuit displayed (Fig. 10)
as a completely assembled and tested
evaluation board from CONCEPT (see
also the section on „Evaluation boards“).
The evaluation board is also equipped
with an electrolytic battery of very low-
inductance design.
