Abstract
A method and apparatus for estimating stress on capacitor is provided. A power converter may include an input terminal for receiving an input voltage, a power stage coupled to the input terminal, a capacitor coupled to the power stage, a controller configured to control the power stage to generate an output voltage at the capacitor as a function of the input voltage, and a stress monitor module. The stress monitor module is configured to determine a stress energy metric for the capacitor based on variations in the output voltage and identify a first fault condition based on the stress energy metric.
