The SpeedVal Kit Half-Bridge Motherboard contains the power connections, DC bus, and interface for the daughter cards. This motherboard supports a single half-bridge configuration with one gate driver card and one power daughter card and is designed for double pulse testing or power buck/boost testing.

The PWM signals for the Silicon Carbide MOSFETs can be supplied externally from a function generator, or by using one of the optional control cards that plugs into the motherboard. The control cards have pre-tested firmware and a computer-based graphical user interface (GUI) that allow the controller to run a double pulse test or operate the evaluation board as a buck or boost converter in both synchronous and asynchronous configurations. The control card and GUI also provide system-level feedback of the input and output voltage and current readings.

Specifications:

DC Bus voltage up to 900V
Input/output current rating up to 40A
Low-inductance layout
Connector for optional control card
Screw terminal power connections
Ideal for double pulse testing and high-power testing
Onboard fan for cooling the Silicon Carbide devices during high-power testing
