On-Board Chargers
The necessity of OBC in cars is important nowadays as the charging station infrastructure is limited. But car manufacturers are trying to minimize the cost, size, and weight of OBC and the required cooling system. This trend fits well with the advantages of GaN technology and more specifically with VisIC’s D3GaN solution. As GaN can switch fast and with the lowest switching losses the passives can be reduced by ½ or ⅓. The low switching losses enable simpler cooling systems and allow to even move to air-cooled OBC solutions to reduce the car cost.
