IGBT to SiC MOSFET: Evaluating TCO and Miniaturization
The key criterion for deciding to switch from IGBT to SiC is not a device-level cost comparison, but rather how SiC-enabled downsizing of cooling systems and passive components changes the overall system BOM cost and product specifications. This article organizes application-specific decision frameworks and hybrid SiC as an intermediate solution.

AI Server Power Supplies: GaN Adoption Criteria
Deciding whether to adopt GaN in AI server power supply design isn't solely based on it being "next-generation technology"; it requires confirming GaN's clear advantages over SiC and Si along the three axes of switching frequency, power density, and thermal design.
SiC vs. GaN for EV Applications: Choosing the Right Material
The adoption of 800V battery systems is accelerating, exemplified by the Porsche Taycan, Hyundai IONIQ 6, and Kia EV6, all of which have transitioned from traditional 400V architectures to double the voltage to shorten charging times and improve driving efficiency, a trend directly impacting power device selection, as evidenced by Si
GaN Power Semis: Miniaturization and Efficiency Benefits
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).
Are IGBTs Still Relevant in the Age of SiC and GaN Silicon?
The long-heralded transition of power in the power conversion market is underway, with the SiC power device global market projected for rapid expansion towards the 2030s, and GaN adoption broadening from home appliances to data center power supplies. This raises the question about Silicon IGBTs...
Power Semiconductor Market Restructuring Map 2026
While the SiC power semiconductor market is projected to reach approximately $3 billion in 2025 and exceed $10 billion by 2030 according to multiple research firms, the current industry focus has shifted from "growth" to "realignment," with the question now being less about who will capture the market and more about who will survive.
