Frequency Estimation for Grid-Tied Inverters Using Resonant Frequency Estimator

open access: yesEnergies, 2021
This paper introduces a new strategy of frequency estimation for grid-tied and stand-alone mode AC/DC power converters. Frequency stabilization is required, especially when operating in stand-alone mode with a Droop Control strategy, or in hybrid mode ...

A Fast Background Frequency Calibration Based on Intermittent Frequency Locked Loop for the Super-Regenerative Receive

open access: yesIEEE Access, 2022
The conventional phase-locked loops or frequency-locked loops should take time to calibrate the oscillator’s resonant frequency in a super-regenerative receiver (SRR) and severely disrupts the receiver’s operations.
