Designing a good GDT is not hard; typically, any ferrite core designed for transformer usage will work, but toroids are preferred. Our expertise is transferable to many industries and our projects reflect this diversity. Pattern Imprinted Concrete and Brick Walls.

What We Do. Any leakage inductance manifests itself as additional inductance in series with the gate.

This floating drive signal can be provided in several ways. For example, consider the following table, taken from the datasheet of a large IGBT module:. Pattern Imprinted Concrete and Brick Walls.
