3 Jumpers and Switches
This chapter describes the jumpers and potentiometers to configure the various features of
the evaluation board. The default settings are shaded in the following tables.
3.1 Power Supply (JP: 15, 18, 19, 20, 22, 23)
The evaluation board supports a variety of different input voltage combinations. The analog
and logic regulator input supply can be provided either by a separate power input (X15), by
the gate driver supply voltage or it can be connected directly to the DC link. The supply
voltage for the gate drive circuits must be in the range of 10-20V and can be derived either
from the DC link input (X11) or X15. A 15V voltage regulator can be inserted in case the
used input voltage is higher than 20V.
JP15 VCC15V Source
JP18 DC link power connect
JP19 This jumper can be used to connect the DC link and/or gate driver supply to the
JP20 Power
JP22 5VReg_source
JP23 GND_connect
This jumper selects whether the gate driver supply voltage is fed from the 15V
voltage regulator or directly from the DC input voltage
This jumper connects the DC link voltage input X11 with the logic and gate driver
supply. To vary the DC link voltage from 0-35V independently of the other supply
voltages, open JP18 and supply the logic input voltage by X15.
supply input X15. This can be useful when a small motor is used and the entire
system is powered by X15 (JP18 closed), or when JP18 is open, it is also possible to
supply the gate driver from X15 and the DC link by X11 (default setting).
This jumper can be used to switch the logic supply on and off.
This jumper selects whether the input for the 5V regulator is X15/JP19 or the gate
supply input voltage. In case the voltage at X15 is higher than ca. 18V, it is re-
commended to set the 15V regulator as gate supply source and input to the 5V
regulator.
This jumper connects the power ground with analog ground.
