I/O explanation of the evaluation board
For a single module drive, please use a through hole to short
the pattern in the common mode choke connected area.
Please attach this board only when performing a parallel drive
in the common mode choke. Common mode choke is not
connected initially.
Please adjust the Rgon, Rgoff as required by circuit conditions,
the initial suggested values are shown in the table to the left.

Connect CN8-1, CN8-2, CN8-3 and CN8-6 on the sub board to CN2. Don’t use
CN3 when single module driving.
Connect CN9-1 and CN9-2 on the sub board to CN4. CN5 can be used instead of
CN4 even if single if single module driving.
Connect CN10-1 and CN10-2 on the sub board to CN6. CN7 can be used instead
of CN6 even if single if single module driving.
Connect T1C on the sub board to T1 collector terminal as shown in page 6.
Don’t operate the IGBT without connecting T1C and T1 collector terminal.

Please adjust balance resistances according to circuit conditions.
Balance resistance is attached to the parallel drive. (Initial value:
R=0Ω)
DO NOT REMOVE RESISTORS R45,R46,R47 AND R48.
These resistors discharge stored gate energy during short circuit
protection.
The sub board is equipped with an active clamp, please use if deemed
necessary. As for the 4MBI300VG-120R-50, There is no need for
active clamp circuit. Active clamp diode is not attached initially.

The T1 and T2 gate drive circuit has a bult-in function of short-circuit protection. The DESAT
pin monitors a short circuit. When a DESAT fault is detected, the IGBT is turned off softly.
The soft turn-off speed is adjustable by changing the value of resistances R46 and R47.
The soft turn-off circuit is different from the typical gate drive circuit on the datasheet of
AVAGO ACPL-339J (AV02-3784EN)

When the DESAT fault is detected, the IGBT is turned off and FAULT output switches
from high to low.
Please refer the data sheet for AVAGO ACPL-339J (AV02-3784EN) for more detail.
