Dynamically-compensated controller |
摘要 |
A dynamically-compensated controller may generate a switching signal for a DC power supply. The controller may include a feedback circuit having a first analog-to-digital converter and a separate analyzer circuit for generating information indicative of performance characteristics of the feedback circuit based on information about the results of a test perturbation signal at an output of the DC power supply. The analyzer circuit may include a DC removal circuit configured to substantially filter out the DC component of the results of the test perturbation signal at the output of the DC power supply, a frequency translation circuit configured to translate the frequency of the filtered signal to a frequency that is lower than the frequency of the test perturbation signal, and a second analog-to-digital converter different from the first analog-to-digital converter that is configured to generate a signal representative of one or more of the characteristics of the filtered signal. |
