采用IA-PIM数字再设计方法，对LLC谐振DC-DC变换器的模拟积分控制器进行离散化，设计了数字脉冲频率调制控制器。它通过调整输入开关频率来调节输出电压，进而改变LLC转换器的增益。通过大量的仿真，其性能的负载突变进行评估。这些结果表明，数字控制器可以在比当前流行的采样频率低得多的采样频率下实现模拟控制器的性能，这在降低计算要求和功耗方面可能是有利的。
A digital pulse-frequency-modulated controller is designed by discretizing an analog integral controller for an LLC resonant DC-DC converter using the so called IA-PIM digital redesign method. It regulates the output voltage by adjusting the frequency of the input switching, which in turn changes the gain of the LLC converter. Its performances to sudden changes in the load are evaluated though extensive simulations. These results show that the digital controller can realize the performance of an analog controller at a sampling frequency that can be much lower than those currently prevail, which may be advantageous in terms of reduced computational requirements and power consumption.
