Manual for HybridKIT Evaluation Gate Board
HybridKIT Evaluation Gate Driver Board for 750V EDT2 IGBT
Feature and Limitations Overview
3.3
Recommended Operating Conditions
The following recommended operating conditions describe the targeted lab testing environment.
Testing beyond the given area may be possible in specific cases when all individual parts are driven within their
specification. On the other hand the evaluation gate driver board together with the power module should not
be regarded as a protected system. It is not a considered product for end customers. The intention of the
evaluation gate driver board is to support engineers in their first steps designing with the Infineon EICEDrivers
and HybridPACKs. Please see also the section 3.4 in order to understand the limitations.

The operating temperature is mainly limited by the power dissipation of the power supply implemented on the
evaluation kit board. The gate drivers, gate resistances are not the limitation in this design.

Limitations of the Evaluation Kit
The gate driver board with the power module should not be regarded as a protected system. It was designed
for evaluation under lab conditions with minimum automatic shutdown routines. The design was intended to
be usable also under extreme conditions where protection mechanism would limit the evaluation possibilities.
The evaluation gate driver board is not protected against:
Over- & undervoltages on the signal connectors.
Overvoltages of the HV working voltage
(>550V may damage the clamping diodes and/or lead to IGBT short circuit destruction)
Overtemperature of the PCB and module.
The power module NTC temperature info can be obtained as digital signal, but no shutdown limit is set
by the gate driver board.
Testing at high switching frequencies may require an active cooling of the gate driver board especially
at high ambient temperatures.
Please read and understand the manual and the safety warnings (see section 1.1).
Please note that the list are giving examples and should not be seen exhaustive.
