Abstract Details

2024, Master of Science, Miami University, Electrical and Computer Engineering.
Silicon Carbide (SiC) MOSFETs are seeing a higher demand with the increased electrified automobiles and aircraft. Manufacturers produce SiC MOSFETs in many different packages, from bare dies to discrete packages to integrated power modules. The transportation sector requires higher current power conversion, and in some applications, it is unclear whether to use parallel power devices or a power module. This research compares the abilities of commercial off-the-shelf (COTS) power module packages and parallel discrete devices in TO-247 packages for higher current applications. Power modules from Wolfspeed and GE Aerospace are compared with each other and TO-247-4 packaged discrete devices from Microchip Technology and Qorvo. The following thesis contains the motivations behind this research, a literature review about SiC MOSFET packages and current sharing between parallel MOSFETs, the procedure and current progress of this research, printed circuit board (PCB) layouts for the devices, and experimental results using a double pulse test and an efficiency test utilizing a boost converter configuration. Finally, a conclusion with future work is presented.
