The aposyila of the complete system is verified by numerical simulation and experimental results, validating the proposed model and elletronica strategy. Send link to edit together this prezi using Prezi Meeting learn more: Equation 12 is obtained based on the instantaneous power relationship.

Currents i, i and iAC side simulation. Reset share links Resets both viewing and editing links coeditors shown below are not affected. This fact make possible the use of three independent dead beat controllers potencja spite of the existing coupling between the three phases.

Block diagram of system: The performance of the control algorithms is verified by simulations using MatLab and by an experimental setup using a low power converter.

No previous knowledge of discrete control theory is aposhila. Tags eletronica de potencia.

Abstract —A full digital control of a voltage source converter VSC rectifier is presented. For three-phase, higher power applications, requiring bi-directional power flow, a threephase, full bridge, self-commutated converter operating in pulse width modulation PWM mode is a convenient choice [7].

The line current ir t will not track the reference current, presenting amplitude and phase error Fig. The DC loop is active, as can be seen in Fig. For three-phase, higher power applications, requiring bi-directional power flow, a threephase, full bridge, self-commutated converter operating in pulse width modulation PWM mode is a convenient choice [7].

Terminal G2, not present in the real converter, is used here in order to simplify the equivalent circuit modeling.

Its corresponding sinusoidal output rv is obtained through a error In each cycle, the error apostilla or advancement related to voltage zero crossing is calculated by the PLL.

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 Df side. In this case, the converter output is considered constant and equal to its local average during the sample interval.
