The controller design of three-phase controlled rectifier using an adaptive tabu search algorithm

This paper presents a controller design for a three-phase controlled rectifier using an adaptive tabu search. The averaging model of the power electronic system is used as an objective function instead of the model from software packages. The results show that the proposed method can efficiently obtain the best performance of the output waveform compared with the classical method. Moreover, this approach is convenient and flexible for electrical engineering to design the controller of power electronic systems with good performances.

Modeling of three-phase controlled rectifier using a DQ method

Power converter models are normally time-varying because of their switching behaviors. This paper presents the DQ modeling method to eliminate the switching action to achieve time-invariant model. The power system studied is the AC distribution system. The small-signal model of the power system is obtained by using a linearization technique. The small-signal simulations are used to validate the DQ linearized model. The results show that an excellent agreement between the mathematical model and the three-phase benchmark model is achieved.
