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（12V）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。

ST拥有广泛的分立式半导体产品，包括符合AEC-Q101标准的IGBT以及硅和碳化硅（SiC）MOSFET和二极管，符合AEC-Q100标准的电流隔离IGBT和MOSFET栅极驱动器，以及SPC5 32位汽车微控制器，可提供可扩展、高性价比和高能效的解决方案，以实现这些充满挑战性的转换器要求。
