ABSTRACT:
A digital controller configured to inject a signal into a digital feedback path that facilitates regulation of a power converter and measure the corresponding phase, gain, or frequency. The digital controller may also include an adaptive tuning controller for adjusting power converter operating attributes based in part on the measurements. In an exemplary embodiment, the adaptive tuning controller uses the phase, gain, and/or frequency measurements to adjust the digital feedback signal. In an exemplary embodiment, the adaptive tuning controller compares the operating measurements with desired values and generates adjusted operating attributes. In accordance with an exemplary embodiment, the monitoring and adjusting of the digital feedback signal occurs while the digital controller is regulating a power signal in the power converter.
