お客様の FRDMGD31RPEVMハーフブリッジ評価キット
1. Out of the Box
The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the FRDMGD31RPEVM board.

2.2 Board Description
The FRDMGD31RPEVM is a half-bridge evaluation board populated with two GD3160 single channel IGBT or SiC gate drive devices. The board supports connection to an FRDM-KL25Z microcontroller for SPI communication configuration programming and monitoring. The board includes DESAT circuitry for short-circuit detection and implementation of GD3160 shutdown protection capabilities.
The evaluation board is designed to connect to a RoadPak SiC metal-oxide-semiconductor field-effect transistor (MOSFET) for evaluation of the GD3160 performance and capabilities.
2.3 3.3 V to 5.0 V Translator Board
KITGD3160TREVB translator enables level shifting of signals from MCU 3.3 V to 5.0 V SPI communication.
2.4 Kinetis KL25Z Freedom Board
The Freedom KL25Z is an ultra low-cost development platform for Kinetis L series MCU built on Arm Cortex-M0+ processor.

3. Configure Hardware
3.1 Configure the Hardware
The FRDMGD31RPEVM is connected to a compatible SiC MOSFET RoadPak module with a DC link capacitor. Double pulse and short-circuit testing can be conducted using a Windows based PC with FlexGUI software.
Suggested equipment needed for test:
- Rogowski coil high-current probe
- High-voltage differential voltage probe
- High sample rate digital oscilloscope with probes
- DC link capacitor (power ring 700D407 425 μF, 900 V DC)
- SiC MOSFET RoadPak module
- Windows based PC
- High-voltage DC power supply for DC link voltage
- Low-voltage DC power supply for VSUP +12 V DC gate drive board low-voltage domain
- Voltmeter for monitoring high-voltage DC link supply
- Load coil for double pulse and short-circuit testing
4. Install Software
Software for FRDMGD31RPEVM is distributed with the FlexGUI tool (available on NXP.com). Necessary firmware comes preinstalled on the FRDM-KL25Z with the kit.
Even if the user intends to test with other software or PWM, it is recommended to install this software as a backup or to help debugging.
4.1 Install FlexGUI On Your Computer
The latest version of FlexGUI supports the GD3100 and GD3160. It is designed to run on any Windows 10 or Windows 8 based operating system. To install the software, do the following:
- Go to FlexGUI Software and click Download
- When the FlexGUI software page appears, click Download and select the version associated with your PC operating system
- FlexGUI wizard creates a shortcut, and an NXP FlexGUI icon appears on the desktop. By default, the FlexGUI executable file is installed at
C:\flexgui-app-des-gd31xx.exe. Installing the device drivers overwrites any previous FlexGUI installation and replaces it with a current version containing the GD31xx drivers. However, configuration files (.spi) from the previous version remain intact
4.2 Configure the FRDM-KL25Z Microcode
By default, the FRDM-KL25Z delivered with this kit is preprogrammed with the current and most up-to-date firmware available for the kit.
A way to quickly check that the microcode is programmed and the board is functioning properly, is to plug the KL25Z into the computer, open FlexGUI and verify that the software version at the bottom is 6.4 or later.
If a loss of functionality following a board reset, reprogramming or a corrupted data issue, the microcode may be rewritten per the following steps:
- To clear the memory and place the board in bootloader mode, hold down the reset button while plugging a USB cable into the OpenSDA USB port
- Verify that the board appears as a "Bootloader" device and continue with step 3. If the board appears as KL25Z, you may go to step 6
- Download the "Firmware Apps" .zip archive from the PEmicro OpenSDA webpage (OpenSDA ). Validate your email address to access the files
- Find the most recent
MDS-DEBUG-FRDM-KL25Z_Pemicro_v***.SDAand copy/drag-and-drop into the "Bootloader" device - Reboot the board by unplugging and replugging the connection to the "OpenSDA" port. Verify now that the device appears as a KL25Z device to continue
-
Locate the most recent KL25Z firmware, which is distributed as part of the FlexGUI package
- From the FlexGUI install directory, which is located in the
flexgui- app-des-gd31xx\binfolder and is named in the formflexgui-fw- KL25Z_usb_hid_gd31xxC_v0.3.0.bin - This .bin file is a product/family-specific configuration file for FRDM-KL25Z containing the pin definitions, SPI/PWM generation code and pin mapping assignments necessary to interface with the translator board as part of FRDMGD31RPEVM
- From the FlexGUI install directory, which is located in the
-
With the KL25Z still plugged through the "OpenSDA" port, copy/drag-and-drop the .bin file into the KL25Z device memory. Once done, disconnect the USB and plug into the other USB port, labeled "KL25Z"
- The device may not appear as a distinct device to the computer while connected through the KL25Z USB port, this is normal
-
The FRDM-KL25Z board is now fully set up to work with FRDMGD31RPEVM and the FlexGUI
- There is no software stored or present on either the driver or translator boards, only on the FRDM-KL25Z MCU board
All uploaded firmware is stored in non-volatile memory until the reset button is hit on the FRDM-KL25Z. There is no need to repeat this process upon every power up, and there is no loss of data associated with a single unplug event.
