摘要：
Methods, apparatuses, and systems for measuring impedance spectrum, power or energy density, and/or spectral density using frequency component analysis of power converter voltage and current ripple are described herein. An example method for measuring impedance spectrum, power spectrum, or spectral density can include measuring an alternating current (AC) ripple associated with a power converter, where the AC ripple includes an AC current ripple and an AC voltage ripple. The method can also include performing a frequency analysis to obtain respective frequency components of the AC current ripple and the AC voltage ripple, and calculating an impedance spectrum, a power spectrum, or a spectral density of an electrical component based on the respective frequency components of the AC current ripple and the AC voltage ripple.
