Abstract
These present disclosure provides techniques to determine the capacitance of a power loss capacitor based on voltage ripple. The power loss capacitor may be a power loss capacitor for a power loss shutdown system of a solid state drive. The capacitance may be determined as a function of the voltage ripple and a period of the voltage ripple during a natural discharge and a controlled discharge of the power loss capacitor.
