摘要
LLC谐振变换器具有全范围内实现软开关、低EMI、高功率密度等优势,在通信电源、LED、车载电源等领域内被广泛应用。输出宽范围的条件下,针对谐振腔计算过程,在低谐振频率处提供一种波形模板计算方式,从而得出准确的谐振器件参数。在Simplis平台对LLC谐振期间参数进行仿真,仿真结果验证了参数设计的合理性。
The LLC resonant converter has the advantages of soft switch,low EMI,high power density,etc.It is widely used in communication power supply,LED,vehicle power supply and other fields.Under the condition of wide output range,for the calculation process of resonator,a waveform template calculation method is provided at the low resonant frequency,so as to obtain the accurate parameters of resonator.The parameters of LLC during resonance are simulated on the platform of Simplis.The simulation results verify the rationality of the parameter design.
