UCC25600: 使用UCC25600时，设计LLC半桥所遇到的问题

       I designed an LLC half-bridge resonant boost converter using a UCC25600 controller. The resonant converter has a wide input voltage range of 80V~100V and an output of 450V. The converter has a resonant inductance of 2uH, a resonant capacitance of 800nF, a transformer excitation inductance of 7uH, and a resonant frequency of 130kHz. When I use the DC power supply to output 90V to supply the LLC, I find that the DC power supply has a lot of noise when working, is the reason that the resonance parameters of the LLC I designed are unreasonable?

中文：我使用UCC25600控制器设计了LLC半桥谐振升压变换器。谐振变换器宽输入电压范围80V~100V，输出450V。变换器的谐振电感2uH，谐振电容800nF，变压器励磁电感7uH，谐振频率130kHz。当使用直流电源输出90V供给LLC，发现直流电源工作时有很大的噪声，原因是我设计的LLC谐振参数不合理吗？
