48V电气系统优于目前的12V系统，在为风扇、泵、电动助力转向系统和压缩机供电时提供4倍的功率和更高的效率。虽然高压意味着效率更高，但汽车法规要求如使用高于60V的系统时要使用相对昂贵的屏蔽电缆（以便进行电流隔离），因此48V系统可降低成本。 在轻度混合动力车辆中使用的48V系统是企业推动汽车电气化发展的第一步，不仅性价比更高，还可减低排放量。 ST的产品种类齐全，包括硅功率MOSFET、保护元件、栅极驱动器和微控制器，符合AEC-Q100和AEC-Q101标准，可构建经济高效的48V车辆设备。
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。

轻混动技术为汽车制造商减少CO2排放和提高燃油效率提供了一种经济高效的解决方案。起动机发电机为48 V网络提供电力，降低了ICE负载，并能提供其他功能（如惯性滑行）。起动机发电机可采用皮带驱动（通常为10 kW），也可更深度地集成到车辆的传动系统中，具体取决于需要的动力。
