Junction temperature and luminous flux prediction for white LED array based on electrical-photo-thermal modeling

During the operation of an LED array, its thermal and optical performances are always not equal to the superposition of the individual LED's characteristics because of a significant thermal coupling effect between the arrays. Based on this, this paper proposes an electrical–photo-thermal model, with considering both junction temperature and...

A Thin and Low-Inductance 1200 V SiC MOSFET Fan-Out Panel-Level Packaging With Thermal Cycling Reliability Evaluation

SiC MOSFET is mainly characterized by the higher electric breakdown field, higher thermal conductivity, and lower switching loss enabling high breakdown voltage, high-temperature operation, and high switching frequency. However, their performances are considerably limited by the high parasitic inductance and poor heat dissipation capabilities...
