GaN Modules Boost Switching Frequencies While Maintaining Efficiency

In 2012, we finally got real insight into gallium-nitride (GaN) power devices. Efficient Power Conversion (ePC) published a 200-page textbook about the devices.1 If you want to understand how to compare figures of merit for GaN and silicon devices, for example, it’s there on page 24. International Rectifier (IR), meanwhile, disclosed the architecture of its first GaN products, the IP2010 …
