摘　　要：根据通讯电源的特点,本文分析了LLC谐振半桥的原理,给出了LLC谐振电容、谐振电感和励磁电感的设计方法;同时采用UC3846作为稳压电源调制芯片,并介绍它的功能、特点以及工作原理;最后本文搭建了一个实验样机,证实了UC3846外围电路的可行性。According to the characteristics of the communication power, the paper analyzes the principle of the LLC resonant half-bridge and gives the design method of the LLC resonant capacitor, a resonant inductor and the magnetizing inductance. At the same time, this paper uses the UC3846 as a stabilized power supply modulation chip and introduces its features, characteristics and working principles. Lastly, this paper builds an experimental prototype to prove the feasibility of UC3846 periphery circuit.
