Preliminary Description & Application Manual
Driver solution for 17mm dual IGBT modules with an electrical interface for
2-level, 3-level and multilevel converter topologies with paralleling capability
Abstract
The 2SP0115T is a dual-channel driver with an electrical interface. The driver is based on CONCEPT’s
SCALE™-2 chipset, a highly integrated technology for the reliable driving and safe operation of IGBTs.
Perfectly matched driver versions are available for all 17mm dual IGBT modules. The plug-and-play capability
of the driver allows immediate operation after mounting. The user needs invest no effort in designing or
adjusting it to a specific application.

Preliminary Description and Application Manual
System Overview
The 2SP0115T are plug-and-play drivers based on the highly integrated SCALE-2 chipset developed by
CONCEPT /1/. This is a set of application-specific integrated circuits (ASICs) that cover the main range of
functions needed to design intelligent gate drivers. The SCALE-2 driver chipset is a further development of the
proven SCALE technology /2/.
The basic topology of the 2SP0115T driver is shown in Fig. 2. The values for the gate resistors and other key
components can be found in the specific datasheets for a given IGBT module /3/.
Fig. 2 Basic schematic of the 2SP0115T driver
The driver contains all necessary components for optimal and safe driving of the relevant IGBT module:
smallest gate resistors in order to minimize switching losses, gate clamping, active-clamping diodes
(overvoltage protection at turn-off), V
CE
monitoring (short-circuit protection) as well as the input electrical
connector X1. Moreover, it includes components for setting the turn-off trip level, the response time and the
dead time between both channels in half-bridge mode. Its plug-and-play capability means that it is ready to
operate immediately after mounting. The user needs invest no effort in designing or adjusting the driver to a
specific application.

The Six Steps to Success
The following steps point out the easy way to use 2SP0115T drivers in power converters:
1. Choose a suitable driver
When applying 2SP0115T drivers, you should note that they are specifically adapted to a particular type of
IGBT module.
The type designation of the driver consequently also includes a number corresponding to a specific IGBT
module (see “Ordering Information”).
These drivers are not valid for IGBT modules other than those specified. Incorrect use may result
in failure.
2. 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 60747-1, 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.
The driver can be easily mounted onto an IGBT module by soldering the corresponding terminals.
3. Connect the driver to the control electronics
Connect the driver plug X1 to your control electronics and supply the driver with a voltage of 15V.
4. Select the operating mode
The operating mode can be set with input MOD (interface X1: pin 17). For details, see page 10).
5. Check the driver function
Check the gate voltage: For the off-state, the nominal gate voltage is specified in the relevant data sheet /3/.
For the on-state, it is 15V. Also check the input current consumption of the driver without clock signals and at
the desired switching frequency.
These tests should be performed before installation, as the gate terminals may otherwise not be accessible.
6. Set up and test the power stack
Before starting up the system, it is recommended that each IGBT module be checked separately under power-
cycling conditions. It is usually sufficient to apply the single or double-pulse technique. CONCEPT specially
