In the race to reduce emissions in aerospace systems, designers are increasingly moving towards more efficient electronics in control systems, including those that replace pneumatics and hydraulics–everything from onboard alternators to actuators and auxiliary power units.

Microchip Technology, working with European Commission consortium member Clean Sky, has developed a family of SiC-based power modules for aerospace applications intended to enable more efficient and compact power conversion and engine drive systems. The modules–designated BL1, BL2, and BL3–use a mix of 1200V silicon carbide (SiC) MOSFETs and 1600V diodes on a modified substrate designed for harsh aviation applications. The power modules are also available with Trench4Fast silicon IGBTs…
