RDGD31603PSMKEVM three-phase inverter kit
Figure 33. Connecting the FRDM-KL25Z, translator board, and the RDGD31603PSMKEVM
6.1 Start using the kit
To get started using the RDGD31603PSMKEVM:
•
Assemble the KL25Z microcontroller board, the translator board and the three phase
board together, as shown in
, on the eMPack module.
•
Connect the KL25Z via USB to a computer with FlexGUI software installed.
•
Supply the board with 12 V DC (1.0 A compliance current) through J1. See
polarity and location.
•
Check and adjust auxiliary supplies:
1. Set each VEE voltage (in the range -1.25 V to -7.5 V) using the six left-most
potentiometers shown in Fig.5. For example, adjust R239 to set the VEE voltage of
phase W low-side, measuring between the VEELW and GNDLW test points.
2. Set the VCC+VEE voltage for both low-side and high-side devices, by adjusting R235
and R265 respectively, until the desired VCC voltage is achieved.
Connection with the FlexGUI software can now be started to configure and check the
driver status.
