In E/E architectures, the powernet supplying the energy from the sources to the loads faces many challenges. Usually, two batteries at different voltage levels provide energy to loads distributed across the car. To meet reliability and powernet stability requirements, high safety standards, up to ISO 26262 ASIL D, must be supported.
With rising power demand and increasingly strict efficiency targets, new energy‑management concepts must minimize both power losses in operation and standby current in parking mode.
ST’s latest smart power distribution architectures, combining STi²Fuse smart switches with Stellar 32‑bit automotive MCUs, enable safe and flexible power networks that reduce wire‑harness weight, length, and cost, while improving electric‑vehicle performance and driving range.

48V-12V双向DC/DC转换器
在轻度混合动力电动汽车中，DC/DC转换器是系统不可或缺的组成部分。它通常用于降压模式，将48 V启动发电机产生的电能供给12 V系统。在某些情况（如启动车辆和自动驾驶功能）下，也可用于升压模式。
