电源和变换器

设计电源或变换器时，没有什么秘密可言：无论最终用途是什么，它们必须提供高效率，以满足国家和国际标准（包括80 plus®、ERP Lot6和能源之星）的要求，以及功率密度、可靠性和安全性，而所有这些都必须成本适中。为了找到最好的应用解决方案，设计人员必须选择最有效的功率拓扑（反激、升压或准谐振）或者实现基于单片集成电路或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。 ST广泛的产品组合包括高度集成的AC-DC变换器和控制器、单片DC-DC变换器、硅和碳化硅（SiC）功率MOSFET和整流器、IGBT和保护IC、线性稳压器、电池管理IC（包括无线电池充电器IC）、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变换器。 Read more
