このドキュメントの内容

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 FRDMGD31ECNEVM board.

2.1 Board Features

  • Capability to connect to MOSFET or IGBT modules with an EconoDUALTM footprint for half-bridge evaluations
  • Daisy chain SPI communication capable
  • Power supply and fail-safe jumper configurable
  • Easy access power, ground and signal test points

2.2 Board Description

The FRDMGD31ECNEVM is a half-bridge evaluation kit populated with two GD3100 single channel IGBT gate drive devices on a half-bridge evaluation board with pin configuration compatible with Econo IGBTs.

The kit includes the Freedom KL25Z microcontroller hardware for interfacing a PC installed with SPIGen software for communication to the SPI registers on the GD3100 gate drive devices in either daisy chain or standalone configuration.

2.3 3.3 V to 5.0 V Translator Board

GD3100 translator enables level shifting of signals from 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 KL1x (KL14/15) and KL2x (KL24/25) MCUs built on Arm® Cortex®-M0+ processor.

3.1 Configure the Hardware for Startup

The following figure presents a typical hardware configuration.

To configure the hardware and workstation, complete the following procedure:

  1. Connect FRDM-KL25Z and the translator board with FRDMGD31ECNEVM half-bridge evaluation board by attaching to the 24-pin header in the correct orientation
  2. Attach the FRDMGD31ECNEVM to an IGBT module as desired with socket pins firmly on the module pin connections. Half-bridge board jumpers will be pre-installed from the factory and configured for SPI communication in a non-daisy chain SPI configuration
  3. Attach 12 V DC power supply to VPWR connection on half-bridge board and low voltage domain GND test point connection on half-bridge board. Note: Be sure to ground to low voltage domain for VPWR connection.
  4. Connect USB cable from USBKL25Z USB mini connection to Windows-based PC USB port. KL25Z will be pre-installed with firmware from factory
  5. With SPIGEN GUI installed and application running on Window-based PC, reconnect USB cable. A pop-up should appear indicating connection to the FRDM-KL25Z board
  6. Enable the 12 V DC power supply to the VPWR low voltage domain. The SPIGEN GUI enables you to READ and WRITE registers on each GD3100 gate driver on either SPI0 (low-side) or SPI1 (high-side)
  7. Observe VCCL and VCCH voltage levels on the low-side and high-side high voltage domains respectively. These are set to provide the gate drive high levels from the fly-back transformers and are isolated from the low voltage domain and from each other and have isolated grounds. VCCL (low-side) and VCCH (high-side) will be at ~17 V with VEE set to ~-3.3 V, which will be the swing levels of the gate driver PWM signals
  8. With a DC link voltage supplied and an inductive load connected to the IGBT module, double pulse and short-circuit testing can be performed utilizing the SPIGEN pulse test functions in conjunction with the FRDMGD31ECNEVM half-bridge evaluation board. Use test points to observe desired signals

Note: For double pulse and short-circuit tests, ensure J235 and J236 are populated on the translator board. These jumpers need to be open if supplying PWM signal externally.

4.1 Preparing Graphical User Interface Operating Environment

  1. Install the firmware and MCU code
    • The kit ships with KL25Z MCU firmware already installed. If for any reason the KL25Z MCU firmware needs to be re-installed, follow this procedure. Hold down the reset button on the KL25Z board and connect a mini USB B cable from the PC to the programming interface SDA USB port. Release the reset button. The PC shows a drive called E:/BOOTLOADER or something similar. Copy the SDA file (MSD- DEBUG-FRDM-KL25Z_Pemicro_v118.SDA) to the E:/BOOTLOADER drive
    • Unplug and re-plug the USB cable to the same location to restart and activate the new firmware (do not hold the reset button this time). The drive name changes to E:/FRDM-KL25Z or something similar. Copy the file UsbSpiDongleKL25Z_GD3100_545.srec to the E:/FRDM-KL25Z drive. Unplug USB cable. Firmware files are available with SPIGEN install, which can be downloaded from NXP.com and can be found in SPIGEN install directory folder
  2. Run SPIGEN SPI generator software installer to install SPIGEN on PC
  3. Run SPIGEN with KL25Z board connected
    • Connect the PC to the mini USB B cable into the “USBKL25Z” USB port on the KL25Z board
    • Open the SPIGen software on the PC. At the bottom of the page, you should see SPI dongle Firmware Ver. 5.4.7 or later
