Designing 6.6kW bidirectional HEV/EV on-board-charger with SiC and embedded technologies

This series provides an overview of HEV/EV OBC specifications, technology trend, topology selections and design considerations of an OBC system.
In this series of presentations, we go through the HEV/EV market status and history, OBC specifications, technology trends, 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 at the end of this paper to demonstrate the performance of our designs as well as TI SiC and embedded Technologies. The design contains a large variety of our 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.
