RF-HD2 Hybrid Driver

The RF-HD2 Hybrid Driver is a dual IGBT module gate driver based on the Powerex VLA504-01/VLA503-01 hybrid IC for driving n-channel IGBT modules rated up to 400A. This driver is an ideal choice for high power inverter applications such as that in the ReactorForge induction heater. It can drive high current IGBT modules and features short circuit protection via built-in desaturation detectors, keeping the system safe during harsh operation.

For performance characteristics see the datasheets below:

  • Powerex VLA504-01 Hybrid IC Gate Driver Datasheet
  • Powerex VLA106-15242 DC to DC Converter Datasheet

Note: The photos shown here are of board version 1.0 to 1.2, the current version is 1.3. The necessary connections are however the same.
