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 […]

Thermal gap filler incorporates carbon fibers to boost conductivity, maintain flexibility

November 17, 2022 By Lee Teschler

fujipoly

Sarcon CF210A is the newest Fujipoly thermal gap filler and incorporates carbon fibers along with traditional fillers found in thermal gap filler materials. The carbon fibers allow for higher thermal conductivity (21 W/m•K) while remaining compliant. Sarcon CF210A’s compliance is closer to a much lower conductivity gap filler such as Sarcon PG25A. While the thermal […]

Better thermal management of eGaN FETs

February 16, 2022 By Assaad Helou

thermal management

A few simple thermal management guidelines can help conduct heat away from GaN FETs. Assaad Helou, Efficient Power Conversion Enhancement-mode gallium nitride (eGaN) FETs offer high power-density with ultra-fast switching and low on-resistance, all in a compact form factor. However, the power levels these high-performance devices provide can be limited by extreme heat-flux densities. If […]

Sager Electronics to handle Advanced Thermal Systems standard, DIY, tubed and custom cold plates

July 1, 2021 By Lee Teschler

TPP 450

Standard, DIY, tubed, and custom liquid cold plates from Advanced Thermal Systems (ATS) are candidates for cooling high-powered electronics, IGBT modules, lasers, wind turbines, motor devices, automotive components, medical equipment, and other applications where air cooling is insufficient. Liquid cold plates ultimately cool power electronics by transferring heat to liquid that and then dissipating via […]
