A grid frequency estimation method based on moving average filter half-tangent phase-locked loop

open access: yesDiance yu yibiao
This paper proposes a half-tangent phase-locked loop (HTan-PLL) with a moving average filter (MAF) for estimating grid frequency. The proposed PLL utilizes a half-tangent phase detector (PD) and introduces MAF into the phase-locked loop to address ...

Radar Waveform Generator with Fuzzy Frequency Regulation [PDF]

open access: yesInternational Journal of Telecommunications
: The Phase-Locked Loop (PLL) is a common functional component in many electrical systems. Phase-locked loops (PLLs) are closed-loop feedback-driven devices producing a signal depending on the frequency and phase of reference sig-nal that comes in.

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.

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.
