Introduction
The evaluation board EVAL-IGBT-1200V-TO247PLUS was developed as a test platform for 1200V
IGBTs in TO-247PLUS and TO-247PLUS 4pin packages but can also be used for standard TO-247 and
TO-247 4pin packages.
This introductory section provides an overview of the potential applications of the evaluation board and
lists the components included in the delivery.
1.1
Purpose of the board
The main motivation to develop the evaluation board shown in Figure 1 was to have one universal test
platform for 1200V IGBTs in TO-247 as well as TO-247PLUS packages with three as well as four leads.
It allows evaluating the advantages provided by the larger lead frame area of the TO-247PLUS package
as well as the performance improvement given by the Kelvin emitter connection of the TO-247PLUS 4pin
package. For detailed information on these packages refer to application notes [1] and [2], respectively.

Two different modes of operation can be implemented with this board. First, it can be used to investigate
the switching behavior and measure the switching losses of IGBTs and diodes at different conditions.
Parameters like the DC link voltage, the load current, the device temperature as well as the gate
voltages and resistors are easily adjustable. If desired, snubbers can be assembled as well. Second, the
board can be operated as a step-up or step-down DC/DC converter. Thus, it is possible to characterize
and run devices in a continuous mode of operation in the same setup.
Care was taken to minimize the parasitic inductances and capacitances of this board wherever possible.
If needed, board users can tune the parasitic circuit elements by simply adding small capacitances and
inductances.
