The packaging of SiC power devices has relied heavily on the same wire bonding approach used in silicon MOSFETs and IGBTs, largely because of its ease-of-use and low production costs. But while this suits the tens of kHz switching frequencies demonstrated by silicon devices, hit the much higher MHz speeds of SiC systems and parasitic inductances pose a problem.
