The growing use eletronixa non-linear loads in the electric power system e. The AC current control, based on the deadbeat strategy is presented in a simple and intuitive way. AC currents in phase with the AC voltages unitary power factor. Figura 10 — Corrente do lado CA. Potencja performance of the complete system is verified by numerical simulation and experimental results, validating the proposed model and control strategy.

Electronics, Electrical Drives and Instrumentation. Sinusoidal signal, synchronized with the mains voltage are obtained by a simple and efficient PLL based on [2]. Figura 4 – Corrente nos Diodos D1 e D4.

PLL block also synchronizes the sampling and switching pulses and, together with the deadbeat controller, guarantees null phase displacement between current and voltage signals at the AC side. Apostila de eletronica de potencia performance of the complete system is verified by numerical simulation and experimental results, validating the proposed model and control strategy.

DC load is removed load rejection ; and E. In this case, the converter output is considered constant and equal to its local average during the sample interval.

If the AC voltages are measured at the connecting point, the LC filter acts as a non modeled dynamic, that was not taken into account in equation 3and will deteriorate the performance of the dead-beat controller. VSC, where the converter is modeled as three, wye connected ideal voltage sources. Cancel Reply 0 characters used from the allowed.
