Abstract
Systems and methods in accordance with this invention provide a power converter including an input signal terminal, a first output signal at a first output signal terminal, and a controller. The controller is adapted to switch the first output signal from a first value to a second value, measure a voltage at the input signal terminal as a function of time, set a flag to a first flag value if the measured voltage falls below a predetermined value within a first predetermined time interval after the first output signal has been switched from the first value to the second value, otherwise set the flag to a second flag value, and save the flag in a memory. Numerous other aspects are also provided.
