摘要
针对电压型控制LLC谐振变换器动态响应速度较慢的缺点,研究了谐振电容电压控制LLC谐振变换器。与电压型控制LLC谐振变换器相比,该控制无需压控振荡器和电流采样模块,简化了控制回路,减小了变换器整体体积,提高了动态响应速度。详细分析了该控制的工作原理与关键参数设计,最后通过实验与电压型控制进行对比,验证了谐振电容电压控制LLC谐振变换器具有更快的动态响应速度。
Due to the poor dynamic response of voltage controlled LLC resonant converter, resonant capacitor voltage controlled LLC resonant converter is studied.Compared with voltage controlled LLC resonant converter,this control el- iminates oscillator and current sampling module, simplifies the control loop, reduces the overall volume of converter, and improves the dynamic response.The working principle and critical design parameters of this control is analyzed in detail, and compared with the voltage control,the experiments verify that resonant capacitor voltage controlled LLC resonant converter has faster dynamic response speed.
