MITSUBISHI SEMICONDUCTORS POWER MODULES MOS
USING INTELLIGENT POWER MODULES
6.1.3 V-Series IPM Construction
V-Series IPMs are similar to the ce-
ramic isolated types described
in Section 6.1.2 except that an in-
sert molded case similar to the
U-Series IGBT is used. Like the
U-Series IGBT described in Sec-
tion 4.1.5, the V-Series IPM
has lower internal inductance and
improved power cycle durability.
Figure 6.6 is a cross section draw-
ing showing the construction of the
V-Series IPM. The insert molded
case makes the V-Series IPM is
easier to manufacture and lower in
cost. Figure 6.7 shows a
PM150CVA120 which is a 150A
1200V V-Series IPM.
6.1.4 Advantages of Intelligent
Power Module
IPM (Intelligent Power Module)
products were designed and devel-
oped to provide advantages to
Customers by reducing design, de-
velopment, and manufacturing
costs as well as providing improve-
ment in system performance and
reliability over conventional IGBTs.
Design and development effort is
simplified and successful drive co-
ordination is assured by the inte-
gration of the drive and protection
circuitry directly into the IPM. Re-
duced time to market is only one of
the additional benefits of using an
IPM. Others include increased sys-
tem reliability through automated
IPM assembly and test and reduc-
tion in the number of components
that must be purchased, stored,
and assembled. Often the system
size can be reduced through
smaller heatsink requirements as a
result of lower on-state and switch-
ing losses. All IPMs use the same
standardized gate control interface
with logic level control circuits al-
lowing extension of the product line
without additional drive circuit de-
sign. Finally, the ability of the IPM
to self protect in fault situations re-
duce the chance of device destruc-
tion during development testing as
well as in field stress situations.
6.2 IPM Ratings and Characteris-
tics
IPM datasheets are divided into
three sections:
• Maximum Ratings
• Characteristics (electrical,
thermal, mechanical)
• Recommended Operating
Conditions
The limits given as maximum rating
must not be exceeded under any
circumstances, otherwise destruc-
tion of the IPM may result.
Key parameters needed for system
design are indicated as electrical,
thermal, and mechanical character-
istics.
The given recommended operating
conditions and application circuits
should be considered as a prefer-
able design guideline fitting most
applications.
