Thermal management

An overview of Computational Fluid Dynamics (CFD)

June 10, 2025 By Aimee Kalnoskas

Understanding airflow, heat transfer, and fluid behavior is critical when designing high-performance electronic systems. That’s where Computational Fluid Dynamics (CFD) comes in. CFD uses advanced numerical analysis to simulate how fluids — like air or coolant — move through and around complex geometries. For engineers working on thermal management, enclosure design, or aerodynamic optimization, CFD […]

How soft switching and SiC devices improve power conversion

June 5, 2024 By Mike Zhu, Qorvo

By Mike Zhu, Qorvo Soft switching in DC-DC converters reduces energy loss. SiC transistors allow for higher switching frequencies and, thus, smaller magnetics, which reduces heat. Efficiency and power density are both essential factors in the design of power converters. Every contributor to energy loss generates heat that needs removal by costly and power-hungry cooling […]
