This paper proposes a nonlinear decoupled current control scheme for grid-connected inverter with LCL filter. Decoupling the active and reactive channels is one of main demands in inverters. For inverters an L filter, decoupling can be achieved by proper feed-forward grid voltages. However, coupling complex issue converters filters. The resonance mode filter may cause instability, which adds mo...

Capacitor current active damping is a common method to achieve dissipation for LCL -filtered grid-connected converters using grid-side control. However, the dissipative characteristic of converter output admittance near critical frequency can easily be jeopardized by filter parameter deviation....

This paper presents an analysis of the sliding mode control (SMC) method applied to a single-phase grid-connected voltage source inverter (VSI) with L and LCL filters. First, simulation results were presented for filter, then, after some adjustments, same theory was VSI active damping. To improve obtained SMC control, we adopted hyperbolic tangent function explicit establishment modulation inde...

The power electronic converters and grid-connected filters were important components of the permanent magnet direct drive wind generation system whose performance directly determines quality generation. In past modeling, analysis, control studies, capacitive inductive often treated as integral-order components. However, inductance capacitance in actual generator fractional-order components, the...
