1. Introduction
The equipment of power electronics application is
comprised of general use inverters, numeric control
(NC) machine tools, and industrial robots. Recently,
the requirements of lower noise, higher efficiency,
advanced functions, lower price, and downsizing for
these items have been growing.
The power devices used as the equipment of power
electronics applications are progressing toward lower
loss and higher frequency, and the IGBT (insulated
gate bipolar transistor) rather than the bipolar transis-
tor is gaining popularity.
On the other hand, together with lowered loss for
the IGBT, intelligence is achieved by locating the
peripheral circuits such as the driving circuit and
various protective circuits inside the module. It then
becomes possible to shorten the design time at the
power circuit and contributes to downsizing and ad-
vanced equipment function.
In keeping step with the trends of making the
power devices intelligent, Fuji Electric announced the
bipolar transistor type of intelligent power modules
(BJT-IPM) in 1989. In 1992, the J series of IGBT-IPM
(J-IPM) that pursued lower loss was developed and in
1995 the N series of IGBT-IPM (N-IPM) aimed at
lower price and lower noise was developed and pro-
duced. This time, the R series of IGBT-IPM (R-IPM)
pursues higher cost performance, higher reliability and
advanced functions.
The line-up and features of Fuji Electric’s IGBT-
IPMs and the R-IPM are introduced in the following.
2. Fuji Electric’s Conventional IGBT-IPM Line-Up
and Problems
The line-up, performances and features of both the
J-IPM and N-IPM are shown in Table 1. The J-IPM
was developed with particular attention to low loss.
The N-IPM realized low noise (soft switching) and low
loss in order to respond to the market needs of EMC
(electro magnetic compatibility) regulations and to
match the CE mark. Furthermore, the N-IPM is an
IPM with a lower price and higher reliability made
possible by the adoption of new construction and new
materials. The integrated functions are shown in

the input signal is off state and the temperature

4.2 Integration of the control circuit to the IC
The control circuit of IPMs were designed and
evaluated, combining with IGBT chips after ICs were
designed. Therefore, it had to adjust a drive ability of
an IGBT and various protection functions and accom-
plish good noise immunity by using additional parts
other than ICs. It is impossible to achieve a single chip
IC which is not adjustable and has adopted a hybrid
construction combined with various electronics parts.
Consequently, the further downsizing or lowering of
costs is deviously limited. However, the R-IPM solves
these problems through experiments cultivated by the
development of the conventional IPM and the technolo-
gies to be described below.
Integration of the IPM control circuit with the IC
involves an adjusting method with the IGBT and
measures against noise. With the following techno-
loties, the integration of the control circuit to the IC is
successful.
(1) Through simulation technology conducted by a
combination of IGBT characteristics and IC char-
acteristics, the most suitable design is determined
by theoretical study and review of such factors as
the necessary capabilities required for the IC.
(2) The noise immunity is improved by insertion of a
filter on the reference power supply of each circuit
block, and by incorporating a filter into the IC,
formerly provided externally, which results in less
noise on the circuit pattern.
(3) Malfunction are prevented by reducing noise in-
flow. This is achieved by separating the noise
sensitive IGBT ground from the sensing and
protection circuit grounds.
(4) The noise immunity increased remarkably by the
reduction of wiring volume of the control circuit
compared with the conventional IPM through the
integration of the control circuit within the IC.
(5) Low loss and soft switching are realized through
the prevention of influence from outside noise by
locating the IGBT and the IC as close as possible
and through the optimization of the IC so that it
can efficiently drive the IGBT.
The switching waveforms of the J-IPM and the R-
IPM are shown in Fig 8. In particular, the R-IPM
restricts di / dt, dv/ dt at the time of turn-on and
recovery, and realizes soft switching.
Through the measures mentioned above, the num-
ber of electronics parts have been reduced to 1/10 that
of the J-IPM, as shown in Fig. 9.
4.3 Package construction
Facilitated use is taken into consideration for the
newly designed package, maintaining compatibility.
The features are as follows.
(1) Preservation of compatibility of the mounting,
main terminal and control terminal position
(P610, P611 package)
(2) Preservation of endurance against bending frac-
ture through the adoption of metallic guide pins
for the control terminals
(3) Dissolution of a terminal deformation through the
shortening of control terminals
(4) Realization of a thin shape and light weight
through optimization of the internal construction
5. Conclusion
Fuji Electric’s IPMs and the series and features of
the recently developed the R-IPM have been intro-
duced. The R-IPM is the first product to comprise the
IPM utilizing only silicon semiconductors. In addition,
the function which directly detects the temperature of
the IGBT chips has been newly built-in. We firmly
believe that application of the R-IPM contributes to the
downsizing and high reliability of the equipment by a
considerable degree.
Furthermore, making the power devices intelligent
will be promoted more often in the future, together
with the progress of IC technology, corresponding to
the needs for reduced total system costs, downsizing
and high reliability of application products. We resolve
to strive for the development and production of such
products so that we are able to fully respond to the
market’s needs.
