Abstract: Embodiments of the present disclosure describe frequency detection techniques for detecting power irregularities. These irregularities may include variations or abnormalities in switched-mode power supply circuit switching behavior, power spikes, and/or output oscillations. The frequency detection techniques may compare different frequency components of the power signal to detect irregularities.
