摘要 相对于传统的PWM变换器,LLC谐振变换器具有开关频率高,开关损耗小,EMI噪声小和体积小等优点,以及在全负载范围内能实现原边开关管零电压开通,副边二极管零电流关断,而得到广泛应用。为了输出大电流,减小纹波带来的压力,本文在参考大量文献后采用交错并联技术设计了一种LLC谐振变换器,并进一步设计了该变换器的控制补偿器,并得到仿真验证。最后将其离散化,转换成为数字控制器,最后写入程序,实验得到了稳定电压的输出。 Compared with traditional PWM converter,LLC resonant converter has been widely used due to the advantages of high switching frequency,low switching losses,small EMI noise and small volume,etc.By referring extensive literature,the paper has designed LLC resonant converter and its controlling compensator by using interleaving technology,which obtained simulation.Finally the converter has converted into digital controller and written into program,which obtained stability voltage output.
