“…The low-frequency controller characteristics will still be dominated by the series filter inductance. Thus, the transfer Equation (18) can be approximated as follows: Figure 8 shows the Bode plots of the approximation model (20) and the precise model (18). It demonstrates that the cutoff frequency of the system will not be influenced by using the approximation model.…”

“…The active damping method can be used to damp out the resonance at no expense of efficiency. The state variable feedback, such as filter capacitor voltage [15,16] or filter capacitor current [17,18], is introduced to provide virtual resistance. Among them, the capacitor current feedback is a typical and widely used method.…”

“…But delay is inevitable in digitalcontrolled system and the delay will change the system phase-frequency characteristic, thus it will affect system stability. Paper [12] shows regions of active damping control for LCL-filter that a single loop is sufficient to achieve stable above the critical frequency and an active damping is necessary below the critical frequency. The value of the delay also influences the stability and robustness of the system.…”

“…Active damping consists in modifying the controller in the converter. Active damping methods are more selective in their action, they do not produce losses but they typically need extra sensors and they are also more sensitive to parameter uncertainties [12]- [18]. Therefore, both active and passive damping becomes necessary to be developed in order to achieve a stable operation.…”

“…Portanto, a frequência de ressonância está localizada com uma distância segura em relação aos harmônicos de baixa ordem, que aparecem quando a tensão da rede elétrica apresenta distorção, satisfazendo a inequação (6.18). (LISERRE et al, 2005), (BUSO e MATTAVELLI, 2006), ), (PARKER et al, 2014b, (NASCIMENTO FILHO et al, 2014) …”
