Control Cards And Graphical User Interface (Gui) - Wolfspeed SpeedVal MOD-MB-3P-0900V-40A Series User Manual

Control Cards and Graphical User Interface (GUI)

Basic firmware and a computer-based graphical user interface (GUI) are available for use with the control
cards. This base level of firmware incorporates functionality to provide gate signals and monitor current,
voltage, temperature, and fault signals. The GUI provides a way to quickly start testing the dynamic and
power handling performance of the circuit. The GUI provides a connection diagram to guide the user
through the hardware setup and allows the user to change key settings such as switching frequency, output
voltage, and dead time.
Depending on the desired mode of operation and topology, different firmware may be used to support three-
phase inverter power testing, double pulse testing, and buck and boost testing on a single phase.
Advanced motor control algorithms including sensored and sensorless field-oriented control are available
from our partners at NXP and TI. This allows the firmware engineer to use SpeedVal Kit to develop code to
support their eventual product. Developing the firmware with SpeedVal Kit accelerates the design cycle by
providing the complete power system unlike a traditional controller evaluation board, and work can be
started earlier in the design cycle before any new hardware is designed.
