Abstract

一种LLC控制器(100)及控制方法。所述LLC控制器(100)包括依次连接的主控制器MCU(101)、驱动电路(102)以及LLC谐振电路(103)。其中，所述主控制器MCU(101)首先控制所述LLC谐振电路(103)的工作模式为脉冲频率调制模式，其次，当检测到所述LLC谐振电路(103)的工作频率大于或等于预设阈值时，所述主控制器MCU(101)将所述LLC谐振电路(103)的工作模式切换为脉冲宽度调制模式，再次，所述主控制器MCU(101)根据预设的初始占空比计算策略，确定所述脉冲宽度调制模式的初始占空比，最后，所述主控制器MCU(101)根据所述初始占空比向所述LLC谐振电路(103)提供所述脉冲宽度调制模式的驱动信号。该LLC控制器(100)及控制方法有利于提高控制器的控制性能和可靠性。
