摘要
Abstract
Phase-locked loops(PLLs)are undoubtedly the most popular synchronization technique in the power and energy applications. A challenging problem of designing PLLs is the presence of DC offset in their input ,which causes fundamental frequency oscillatory in the phase and frequency estimated by the PLL. The removal of these oscillations is a challenging task because of their low frequency.A novel method to tackle this problem was presented. Modeling and analysis in the frequency domain and time domain were carried out. The parameters of the system were optimally designed. The effectiveness of this approach is verified through simularion and experimental results .关键词
