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 […]
