The reliability of power converters has become a major design concern especially for those mission-critical industrial and aerospace applications required to operate in a harsh environment. There is a need for real-time monitoring techniques that are capable of tracking health status to give an alert signal before a disastrous system failure and furthermore make the early failure prediction due to...
This paper presents the benefits of interleaving three phase voltage source converters (VSCs) to improve the power density. The output harmonics are also analyzed in frequency domain, then design and optimization of coupled inductor and output filter are given. Verifications are carried out through electrical circiut and electromagnetic's FEM simualtions. Finally, the inductor weight are compared...
This paper presents power loss and thermal analysis of SiC power devices in a 50 kW 3-phase high power density converter during operation. The presented loss and temperature estimations include average analysis and transient analysis by using electro-thermal simulations. For this purpose, thermal impedance network of the SiC power module and cold plate prototype are extracted. Transient analysis shows...
