Frequency Estimation for Grid-Tied Inverters Using Resonant Frequency Estimator
Energies, 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 ...

Phase-Locked Loop with Inverse Tangent based Phase Detection
Advances in Electrical and Computer Engineering, 2021 In this paper, a novel closed-loop synchronization algorithm is proposed based on the linear phase angle detection. The linear phase detection is performed by the inverse tangent (atan2) trigonometric function, while the frequency tracking is performed
