Dual-Channel Plug-and-play SCALE IGBT
Driver 2SD316EI for EconoDUAL IGBT
Modules
Abstract
The 2SD316EI is a dual-channel driver based on CONCEPT’s proprietary SCALE chipset,
a proven technology for the reliable driving and safe operation of IGBTs.
The driver is matched to EconoDUAL IGBT modules. Its plug-and-play capability makes
it ready to operate immediately after mounting. The user need invest no effort in
designing or adjusting it to a specific application.

Description and Application Manual
System Overview
The standard package of EconoDUAL modules covers several voltage and current
ratings (e.g. 150, 225, 300, and 450A at 1200 and 1700V). Some driver parameters
must therefore be matched to the relevant module. As shown in Figs. 1 and 2, this is
done by placing all specific components on a separate basic board which is completely
assembled and tested by CONCEPT. (The customer must order the basic board
corresponding to the relevant IGBT module.)

The basic board contains all gate resistors, gate-clamping and active-clamping diodes
(overvoltage protection) as well as the diodes for the collector-sense function (surge-
current and short-circuit protection). Moreover, it includes components for setting the
turn-off trip level and the response time. It contains only the usual through-hole
components and can consequently be easily adjusted by the user to fit any special
needs and applications.
The 2SD316EI driver is a complex PCB equipped with SMD components such as
CONCEPT’s proprietary chipset. It is mounted on top of the relevant basic board by
means of spacer bolts. The standardized 2SD316EI driver matches all modules within
the EconoDUAL series. It is based on the proven SCALE technology developed by
CONCEPT and implemented more than a hundred thousand times. For further
information on this technology, refer to /1/ and /2/.

The Eight Steps to Success
The following steps point out the easy way to design high-power
converters by using 2SD316EI drivers with EconoDUAL modules:
1. Calculate the power dissipation of the IGBT modules
First choose the EconoDUAL IGBT module suited for your application and determine its
specific on-state and switching losses. This data is used to approximate the size of the
required heat sink.
2. Choose a suitable driver / basic board pair
When applying 2SD316EI drivers for EconoDUAL modules, you should note that the
basic boards are specifically adapted to a particular type of IGBT module.
The type designation of the basic board consequently also includes the type designation
of the corresponding module.
These basic boards are valid only for the specified IGBT modules. Neglect of
this warning may lead to failure.
3. Design the power stack
When designing a power stack, be sure to minimize the parasitic inductances.
To speed-up your startup with 2SD316EI drivers for EconoDUAL modules, CONCEPT
offers ready-to-use evaluation systems. For more information please contact CONCEPT.
Some key issues relating to component selection are discussed in /4/.
4. Attach the drivers to the IGBT modules
Any handling of IGBT modules or drivers is subject to the general
specifications for protecting electrostatic-sensitive devices according
to international standard IEC 747-1, Chapter IX or European standard
EN 100015 (i.e. the workplace, tools, etc. must comply with these
standards).
If these specifications are ignored, both IGBTs and
drivers may be damaged.
