EVBD4400
ASSEMBLY:
Figure 3 is a complete schematic diagram of the board.
This schematic indicates an application using MOSFET's.
When IGBT are used, freewheeling diodes (D4&D5) are
typically added.
To assemble the kit, simply solder the MOSFET power
devices included or install devices specific to your appli-
cation. Note gate, drain, source orientation of power
devices when installing on the PC board.
NOTES:
a) The ICs and Power devices are static sensitive and
require special handling.
b) Use any power device that is suitable for your applica-
tion. The PCB was designed to accept devices with TO-
247 packages. Two IXYS power devices are included in
the kit with their data sheet. D4 and D5 are required only
if Q1 and Q2 are IGBTs, and thus are not included in your
kit. (A recommendation for D4 & D5 is in the Bill of
Materials). D6, D7 footprints provide a smaller package or
footprint option.
g) Dead time is provided by timing components R17, C22
and is fixed at roughly 2.5
. See IXDP630 data sheet for
calculation and modification of the dead time value.
c) Use any convenient method of interconnection at GND,
Q1-D, Q2-S,DC-BUS. The hole spacing is a standard
5.08mm and will fit common terminal blocks. (A recom-
mendation for a connector 'P2' that the PCB will accept is
in the Bill of Materials and is available from Digi-Key among
others).
d) For fault detection, R2 is pulled up to the supply voltage
of the front end logic. If the FLT (fault) signal is to be sensed
by TTL logic, remove R2 and connect FLT externally from
P1-5 to +5V through a pull up resistor.
e) For half bridge applications, insert a jumper between
Q1-D and Q2-S.

It is also possible to construct your own pulse transformers
from scratch using the guidelines presented in the discus-
sion located at http://www.ixys.com/t092702.pdf.
f) The gate resistors, R6 and R11, will depend on the power
device size that is used. Twenty two ohm resistors are
installed and should work for most applications.
