解决方案

在电动车辆的各种配置中，DC-DC转换器将HV转换为48V和12V，将48V转换至12V。DC-DC转换器的关键设计要求是损耗低、效率高、体积小和重量轻。有许多架构需要不同种类的半导体设备。意法半导体提供功率设备、具有快速开关二极管的超结MOSFET、具有共同封装二极管的IGBT、SiC MOSFET和低压沟槽栅MOSFET以及STGAP1S gapDRIVE™栅极驱动器。 Read more

双向DC-DC转换器

电动车辆（EV）使用两种不同的电源系统：用于牵引的高压电池（200至450 VDC）和用于为车辆中的所有电器供电的低压（12 V）电池。过去，低压电池使用交流发电机充电，然而，在今天的车辆中，它通过高压电池组进行充电。不过，在特定的电动汽车架构中，这种低压电池也应随时准备好为高压电池组充电，以便为汽车起动提供能量。换言之，为了运行复杂的控制算法，确保实现高效节能的解决方案，车载DC-DC转换器必须是双向的，且具有极高的效率和可靠性。意法半导体拥有广泛的分立式半导体产品，包括符合AEC-Q
