| Abstract | Inductive-capacitive-inductive (LCL)-type line filter is widely used in grid-connected 17 voltage source inverter, since it can provide substantially improved attenuation of switching 18 harmonics in injected currents into the grid with lower cost, weight and power losses than the L-type 19 counterpart. However, the inclusion of third order LCL network complicates the current control 20 design regarding the system stability issues because of an inherent resonance peak which appears in 21 the open-loop transfer function of the inverter control system and near to the control stability 22 boundary. To avoid passive (resistive) resonance damping solutions, due to their additional power 23 losses, the Active Damping (AD) techniques are often applied with proper control algorithms in 24 order to damp the LCL filter resonance and stabilize the system. Among these techniques, the 25 Capacitor Current Feedback (CCF) AD has attracted considerable attention due to its effective 26 damping performance and simple implementation. This paper thus presents a state-of-the-art 27 review of resonance and stability characteristics of CCF-based active damping approaches for a 28 digitally-controlled LCL filter-based grid-connected inverter taking into account the effect of 29 computation and pulse width modulation delays along with a detailed analysis on proper design 30 and implementation. 31 |
