Date: April 1, 2019
In this presentation, we go through the HEV/EV market status and history, OBC specifications, technology trend, topology selections and design considerations of an OBC system. Complete test results of a 6.6kW OBC reference design (Including AC-DC rectifier and isolated DC-DC converter) will be shown in the end of this paper to demonstrate the performance of our TIDesigns as well as TI SiC and embedded Technologies. The design contains large variety of TI products: the C2000 digital controller, high power controllers, isolated gate drivers, current and voltage sensors, high voltage isolation products, and low power DC/DCs, etc.
