System and method to determine a capacitance of a capacitor

A power converter coupled to an output capacitor, comprising:

• a power train configured to convert an input voltage to a nominal output voltage;
• and
• a controller configured to
• ramp up an output voltage of the power converter with a first slope and a second slope,
• receive a first output current of the power converter during a first rise time associated with the first slope and a second output current of the power converter during a second rise time associated with the second slope, and
• compute a capacitance of the output capacitor employing the first and second output currents, the first and second rise times, and the nominal output voltage.
