2SP0320V / 2SP0320S
Description and Application Manual
System Overview
The 2SP0320V and 2SP0320S 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 2SP0320V and 2SP0320S drivers 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/.

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), Vce monitoring (short-circuit protection) as well as the electrical and fiber-
optic connectors. Moreover, it includes components for setting the turn-off trip level and the response time. 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.

Preliminary
The Five Steps to Success
The following steps point out the easy way to use 2SP0320V and 2SP0320S drivers in power converters:
1. Choose a suitable driver
When applying 2SP0320V or 2SP0320S 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 screwing the corresponding terminals.
3. Connect the driver to the control electronics
Connect the driver plug X2 to your control electronics and supply the driver with a voltage of +15V. Connect
the fiber-optic transmitters and receivers.
4. 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.
5. 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
recommends users to check that the IGBT modules switch inside the RBSOA in the worst case condition, as
this strongly depends on the specific converter construction.
Even if only single IGBTs are tested, all the system’s gate drivers must be supplied with energy.
All the other IGBTs are then kept in the off state by applying negative gate voltages. This is
particularly important when switching the IGBTs under test.
The short-circuit behavior can also be verified at this point.
