AlSiC for Hybrid Electric Vehicle Power Modules

AlSiC for Hybrid Electric Vehicle Power Modules

Hybrid electric vehicle power generation and recovery systems also use IGBTs for power conversion (see also IGBT Thermal Management Baseplates).

The need in these applications is obvious.  Often times, especially in the case of the mild hybrid, these systems are designed to fit in the existing engine compartment, with limited space.  As a consequence the power density is very high and requires active cooling usually off the existing automotive cooling loop system.  And there is another constraint - the active cooling is operating at about 80°C and there cannot result in a significant pressure drop.  Systems need to be lightweight and it also needs to provide a significant level of reliability (10 year lifetime).

CPS AlSiC Power Module Pin Fin Coolers

In this case AlSiC is an ideal and proven solution for thermal management reliability for high density power electronic and IGBTs.  The AlSiC fabrication process also allows for extended pin fins in an open structure for low pressure drop for these active cooling requirements.  AlSiC is ideal for these applications because it is lightweight, with a high strength and stiffness so that it meets the weight budget and it is tolerant of the shock and vibration.
