The rapid growth expected in the electric vehicle (EV) market — expected to be as much as 25% CAGR over the next decade — is driven by environmental concerns and government support and enabled by Silicon Carbide (SiC) device technology that addresses the requirements of high efficiency and power density.

The on-board charger (OBC) is one of the key power electronics systems in modern EVs and comprises AC-DC and DC-DC power stages. In today’s mainstream models, 6.6 kW unidirectional OBCs are popular in EVs with 400 V battery systems. However, there is a growing trend toward bidirectional OBCs to support emerging vehicle-to-grid (V2G) services.
