GaN Power Semiconductors: Benefits of Efficiency and Miniaturization

If you've ever wrestled with improving power conversion efficiency by a single point in inverter design, the numbers alone tell you what GaN (Gallium Nitride) has changed: while silicon MOSFETs hit a wall at tens of kHz switching frequencies, GaN handles up to several MHz, enabling smaller passive components (inductors, capacitors).

SiC and GaN Business Opportunities: Evaluation Criteria

SiC or GaN: The next-generation power semiconductor question, while frequently asked in the industry, is somewhat simplistic; though both are wide bandgap semiconductors, SiC and GaN differ in their optimal voltage ranges, switching domains, and cost structures, meaning the answer depends on the application, voltage range, and timeframe under consideration, rather than a simple 'which is superior' approach.
