5 Connectors

The following figure shows the power connection jack X612. This connector is used to

connect an external unregulated DC power supply voltage (8-15V DC) to the evaluation

board.

Connector X6:

It is recommended to use 9-12V input voltage (depending e.g. on gate driver configuration)

to keep the power dissipation to a minimum.

The DC bus power can be supplied either by X6 (when JP29 and JP63 are set and

the current is not higher than 3A) or by J5. J5 is a screw terminal for currents up to

15A. Be aware that there is no protection diode for this input on the board. The

voltage input range depends on the jumper settings as described in chapter 3.2.

It is recommended to use an external protection diode with sufficient current

capability in case the used power supply is not protected against reverse current

sourced from the load flowing into the power supply.

Always connect '+' to the terminal close to the upper board edge, and GND to the one

close to X6.

Further, it is strongly recommended to use a laboratory DC power supply with

adjustable current limitation with this board. Otherwise, in case of software or

hardware malfunctions or false configurations, high currents can flow and damage

the power supply and/or the board and lead to overheating by excessive power

dissipation.

All pins of the microcontroller are directly connected to J1 to J4 as follows:

Connector

The odd pin numbers are located on the one side and the even pin numbers are located on

the other side of the connector. On the PCB, the corresponding pin numbers of the µC are

written next to the connector pins.
