SYSTEMS AND METHODS FOR POWER DETECTION

Abstract: system and method for detecting a power. for example, a system for detecting a power includes: a first signal converter configured to receive a first signal and generate a pulse-width-modulation signal based at least in part on the first signal; a second signal converter configured to receive a second signal and generate a voltage signal based at least in part on the second signal; and a low-pass filter configured to receive the pulse-width-modulation signal and the voltage signal and generate a power detection signal based at least in part on the pulse-width-modulation signal and the voltage signal; wherein: the first signal is either an input current or an input voltage; the second signal is either the input current or the input voltage; and the first signal and the second signal are different.
