1 shows the structure of the proposed converter, which includes a TFM controller, error amplifier (EA), LC filter, and S-R flip-flop.
Moreover, it also makes very simple and easy-to-design passive LC filter. Consequently, the applied technique nullifies the mathematical operations and quite effectively to the external disturbances and uncertainties of the concerned system.
Figure 6 summarizes the derivation of the plant model of the DC wind turbine based on the discrete time-domain modelling approach (Steps 1-8) [42], the transfer function of the output LC filter (Step 9), and SRC#'s control design (Steps 10-12).
However, this output has harmonics, which is filtered by an LC filter. The AC power output is then connected to meet the load requirement.
According to this information, the simple LC filter was designed and all necessary measurements were repeated.
In traditional method [15], the LC filter is designed based on the transfer function of converter output voltage [u.sub.p] to load voltage [u.sub.L] without load and grid impedance.
Compared with L or LC filter, LCL filter ensures a better smoothing output current from APF.
With combination of two inductor, so that the side of inverter can be selected a little more than the inductor of Lc filter and finally the volume, weight and the east of the filter decreases contribute to the output filter, and finally the current power toward the network can have the power factor 1.
Where: [f.sub.c] is the cut-off frequency (resonance) of LC filter.
