3.1.8 SOA of at switching state
The SOA (Safety Operating Area) of series are described as follows;
V
CES
: Maximum rating of IGBT collector-emitter voltage
V
CC
: DC-link voltage applied on P-N terminals
V
CC(surge)
: Voltage between P and N terminals including surge voltage which will be generated due to wiring
inductance between DIPIPM and DC-link capacitor at switching state.
V
CC(PROT)
: Maximum DC-link voltage in which DIPIPM can protect itself when short circuit happens.
Fig.3-1-13 SOA at switching mode and short-circuit mode
In case of switching
V
CES
is the maximum voltage rating of IGBTs for 1200V (or 600V) as withstanding voltage. V
CC(surge)
is
specified to maximum 1000V (or 500V) subtracted 200V or less (or 100V or less) of surge voltage by internal
wiring inductance of from V
CES
. Furthermore, also V
CC
is specified to maximum 900V (or 450V)
because it should be considered about surge voltage by wiring inductance between terminals and
DC-link capacitor, then the maximum Vcc is subtracted 100V (or 50V) from V
CC(surge)
as the margin.
In case of short-circuit
V
CES
and V
CC
(surge) are same definition as the case of switching. Vcc is specified to 800V (or 400V) because
it should be considered about larger surge voltage by wiring inductance at the turning off short-circuit current,
then maximum Vcc is subtracted 200V (or 100V) from V
CC(surge)
as the margin.
