What are the derating and other design considerations when using bimetallic thermal control devices?
Several design factors relate to specifying and using bimetallic thermal control devices and how they are used in systems. The metals and structure of the bimetallic element are of first importance. The selection of those metals impacts the device’s sensitivity and other performance parameters. Derating is especially important for conductive-type devices. The coefficients of linear […]
What’s the difference between cantilever and disk bimetallic thermal control devices?
The physical structure of the bimetallic element that provides thermal control is the difference between cantilever and disk bimetallic thermal control devices. This article begins by reviewing how bimetallic structures are made and operated. It then looks at how they are implemented in cantilever and disk thermal control devices. Two dissimilar metals are joined together […]
How soft switching and SiC devices improve power conversion
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 […]
Power GaN devices minimize cooling needs
Cambridge GaN Devices (CGD) has announced two new packages for the company’s ICeGaN family of GaN power ICs that offer enhanced thermal performance and simplify inspection. Variants of the well-proven DFN style, both packages are extremely rugged and reliable. Developed for CGD, the DHDFN-9-1 (Dual Heat-spreader DFN) is a thin, dual-side cooled package with a […]
