Analysis and improvement of fourth‐order generalised integrator based phase‐locked loop

open access: yesIET Power Electronics, 2021
The fourth‐order generalised integrator is very suitable for single‐phase phase‐locked loop because it can provide orthogonal signal conveniently and block harmonic voltages effectively. In the conventional fourth‐order generalised integrator based phase‐

Design and verification of data acquisition clock circuit based on dual-loop phase-locked loop

open access: yesHe jishu, 2022
Background Digital measurement system based on ADCs (analog-to-digital converter) has higher requirement on the signal to noise ratio (SNR) of sampled data. Among all the factors, the jitter of sampling clock has the most prominent effect on SNR.

An improved method of phase-locked loop grid-connected inverter based on capacitor voltage full feedforward

open access: yesEnergy Reports, 2022
Different from the conventional grid voltage feedforward, the capacitive voltage type full feedforward will not amplify high frequency harmonics, and it can eliminate the capacitor current control and simplify the controller design.
