Event Description

The pace of light vehicle electrification has been accelerating significantly. The driving factors are not just in the form of governmental regulations. There is a grassroots movement to shift toward electrification and abandon the internal combustion engine. Two complicating factors encountered in moving battery electric vehicle (BEV) adoption forward are range anxiety and charging time.

Addressing range anxiety generally results in larger battery capacity. Along with the larger battery, there is a desire for faster charge times. This has been driving a trend toward increasing On Board Charger (OBC) power. While 6.6kW units were common in the past, the expectation is that 11kW and 22kW will dominate going forward. Another element of increasing charging speed is a trend to 800V main battery voltage. Silicon Carbide (SiC) MOSFETs are ideally suited to address these application parameters.

In this webinar we will explore the benefits of SiC MOSFETs in OBC and off-main-battery DC/DC power conversion units of a BEV. As a wide bandgap material, SiC provides significant advantages over both IGBTs and silicon super junction MOSFETs.
