(LS03) - High-Voltage E-Fuse Technology Demonstrator
This class discusses the benefits of SiC E-Fuse technology which combines circuit protection, control, configurability, and diagnostic features into a single solution for high-voltage applications. (Sept 2023)
With the trend toward higher bus voltages, a robust circuit protection strategy becomes even more crucial. Concerns with reliability and slow response time of traditional solutions are forcing designers to consider alternative solutions such as electronic fuse, or E-Fuse, to quickly detect over-currents and protect downstream wiring and sensitive electronic loads. Enabled by SiC technology and designed for 800V electric vehicle battery systems, the auxiliary E-Fuse combines circuit protection, control, configurability, and diagnostic features in a single solution. E-Fuse offers many system-level benefits. As an example, given the resettable nature of an E-Fuse, the need to design for serviceability may be removed, allowing system integrators and vehicle designers more flexibility in packaging without concern for end-user accessibility. In this presentation the benefits offered by SiC-based E-Fuse over the incumbent solutions will be discussed in detail.
