A Beat Frequency Suppression Control Method Based on a Second-order Generalized Integrator
机车电传动, 2021 In rail transit traction systems, due to the use of single-phase recti fiers, the DC input voltage of the inverter contains a ripple component whose frequency is twice the frequency of the grid-side voltage, which will cause the torque and current of the

Multiple second order generalized integrators for harmonic synchronization of power converters [PDF]
2009 IEEE Energy Conversion Congress and Exposition, 2009 This paper presents a new frequency-adaptive synchronization method for grid-connected power converters which allows estimating not only the positive- and negativesequence components of the power signal at the fundamental frequency, but also other sequence components at multiple frequencies. The proposed system is called the MSOGI-FLL since it is based

An Improved Phase-locked Loop Based on Second-order Generalized Integrator
Kongzhi Yu Xinxi Jishu, 2017 Under ideal grid voltage conditions, single synchronous reference frame phase-locked loop (SSRF-PLL) enables fast and accurate phase/frequency detection, however, abnormal grid voltage conditions highly degrade its performance. To overcome this drawback,

A synchronizing signal detection technique for grid voltage based on new CDSOGI-PLL
Xibei Gongye Daxue Xuebao, 2023 When the grid voltage contains many harmonics, the filtering effect of the phase-locked loop based on dual second-order generalized integrator (DSOGI-PLL) is not ideal, and the frequency of synchronous signal extracted through the DSOGI-PLL fluctuates. A
