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 […]
