(b) Equivalent circuit
Fig.1 Appearance and equivalent circuit of IGBT module for
A-NPC circuits
(a) Lower on-state voltage VCE (sat) and less switch-
ing loss due to optimized eld stop (FS) and
trench gate structures
(b) Improved controllability of turn-on di / dt with
gate resistance Rg
(2) Bidirectional switches
For the bidirectional switches T3 and T4 (see Table
2), RB-IGBTs having a rated voltage of 600 V were
used. The RB-IGBT characteristics are as follows.
(a) RB-IGBT has reverse blocking voltage capabil-
ity, and can therefore be connected in a anti
parallel conguration to enable bidirectional
switching.
(b) When a forward gate bias voltage is applied
to cause the chip to exhibit reverse recovery
switching as a FWD, the reverse recovery char-
acteristics are the same as that of a convention-
al FWD.
(3) Conduction loss
An A-NPC inverter circuit, as compared to a con-
ventional NPC inverter circuit, has half the number

Fig.2 Example of current paths in each switching mode
of conducting elements throughout its entire current
path. As a result, conduction loss can be reduced by
approximately 30% compared to a conventional NPC
inverter. Table 2 compares the current paths and on-
state voltages of the conventional NPC inverter and
the A-NPC inverter.
(4) Switching loss
An IGBT module for use in A-NPC circuit differs
from a conventional IGBT module in that it has the fol-
lowing three switching paths as shown in Fig. 2.
(a) Path in which the main IGBTs operate as
switches and the main FWDs operate in reverse
recovery (Mode A)
(b) Path in which the RB-IGBTs switch and the
main FWDs operate in reverse recovery (Mode
B)
