AC-DC变换器

在典型的AC-DC开关电源（SMPS）中，交流电源经过整流和滤波后进入功率因数校正（PFC）级。然后，通过高频调制技术（有时为了减小变压器和电感元件的尺寸而使其超过1 MHz的频率）将其输送到具有所需电压和电流额定值的直流负载。

为了找到最好的应用解决方案，设计人员必须选择最佳功率拓扑（反激、降压或准谐振）或者实现（基于高度集成的转换器或使用离散功率开关和控制器），或者甚至决定使用先进的数字实现。无论他们的选择是什么，合适的半导体产品是满足他们特定设计目标的关键。

意法半导体广泛的产品组合包括高度集成的AC-DC转换器和控制器、硅和碳化硅（SiC）功率MOSFET和整流器、IGBT、保护IC、以及专门设计的数字控制器和STM32微控制器。我们还提供全套硬件和软件评估与开发工具（包括我们的eDesignSuite），帮助工程师设计高效率的电源和转换器。
