Eletronica Potencia – Eletronica_Potencia
The control ;otencia were implemented by using a dedicated DSP digital signal processor specially designed for power apostila de eletronica de potencia applications. Typical applications include rectifiers for AC drives, telecommunication equipments, etc. Many authors, including ref. The DC side PI controller is designed based on the linearized model of the converter.
No previous knowledge of discrete control theory is required. As the voltage between points G1 and G3 is zero, G1 and G3 can be connected for modeling purposes Fig.
This results in eq. 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 . Eletronica Potencia cristian row Enviado por: Eletronica de potencia Eletronica de potencia. Abstract —A full digital control of a voltage apostila de eletronica de potencia converter VSC rectifier is presented.
The design of the DC control loop is carried out by linearizing the converter model and applying a PI controller plus a pre-filter strategy ce accomplish the desired transient performance. Some authors develops the deadbeat approach for the second order plants LC filterand apostila de eletronica de potencia into account the instantaneous variation of the converter output voltage during a switching cycle.
The performance of the control algorithms is verified by simulations using MatLab and by an experimental setup apostila de eletronica de potencia a low power converter. The AC current control, apostila de eletronica de potencia on the deadbeat strategy is presented in a simple and intuitive way.
The performance of the complete system is verified by numerical simulation and experimental results, validating the proposed model and control strategy. Sinusoidal signal, synchronized with the mains voltage are obtained by a simple and efficient PLL based on . Terminal G2, not present in the real converter, is used here in order to simplify the equivalent aposgila modeling. Incrivelmente absorvente do primeiro ao Effect of parameter mismatch is also discussed.
The growing use of non-linear loads in the electric power system e.
This paper applies the deadbeat strategy to the first order apostila de eletronica de potencia L filterand uses an intuitive and simple approach to obtain the controller equation.
In this case, the converter output is considered constant and equal to its local average during the sample interval. VSC, where the converter is modeled as three, wye connected ideal voltage sources. The sum of the three. This digest presents a PWM three-phase rectifier with digital signal processor DSP control, which aims the reduction of reactive power and harmonics at the AC side, and the regulation of the DC side voltage.
