Optimizing GaN HEMT Performance with the Right Gate-Driving Solution

Discover various driving solutions, ranging from a dedicated driver for Infineon's gallium nitride (GaN) based CoolGaN™ GIT high electron mobility transistors (HEMTs) to a universal drive concept addressing the different GaN technologies. Practical application examples and circuit schematics will complement the presentation.

Suppose you want to get best performance in your GaN design. In that case, it is vital to understand the similarities and differences between the various GaN power transistors and their silicon counterparts.

Today we can find three different GaN switch concepts in the 600 V arena:

  • Classic Cascode
  • p-GaN Schottky
  • p-GaN ohmic (Normally-off) GaN transistors

To fully utilize the advantages of each concept, you need to be aware of the key gate driver requirements for the used solution, as they require different approaches.

In this webinar, we will provide an overview of the different GaN concepts and focus on the p-GaN ohmic switch concept, which is the most promising in terms of Figure-of-Merit (FOM) and reliability.

Get to know the gate drive requirements for Infineon’s CoolGaN™ gate injection transistor (GIT) technology, which is based on a hybrid-drain high electron mobility transistor (HEMT) with a p-GaN gate. Various driving solutions are discussed, ranging from a dedicated driver for CoolGaN™ GIT HEMTs to a universal drive concept addressing the different GaN technologies.

Practical application examples and circuit schematics will complement this presentation.
