How GaN is Challenging Silicon: Insights from TDK’s Ralf Higgelke at PCIM

In this GaN Wine Lounge episode at PCIM Nuremberg, EPC’s Maurizio Di Paolo Emilio interviews TDK’s Ralf Higgelke about his journey from power supply design engineer to technology journalist and corporate communications leader. Higgelke explains how this background gives him a holistic view of power electronics and wide bandgap technologies. He argues that GaN and silicon carbide are complementary but that GaN is rapidly encroaching on higher-power domains, highlighting applications in AI data centers, robotics, and future solid-state transformers.
