摘要
全球对降低能耗的需求正在促进节能技术的推广。在70W～500W交流输入电源中,由于LLC谐振转换器(效率通常在90%以上)的效率高于标准电源拓扑,所以其应用越来越广泛。本文阐释了谐振转换器高效的原因,探讨了LLC谐振转换器的功能和优势,最后简要分析了一个采用FSFR2100 LLC谐振转换器的电源。
The global need to reduce energy consumption is driving the adoption of energy saving technologies.For AC input power supplies in the range of 70W to 500W,LLC resonant converters are being used more and more because they have a better efficiency than alternative standard power supply topologies.Efficiencies of well over 90%are usual.This paper explained why resonant converters are efficient and discussed the function and benefits of LLC resonant converters before briefly reviewing a power supply using the FSFR2100 LLC resonant converter.
