Abstract
En 中文
The aim of this paper is to introduce power quality added function to the standard Vienna rectifier in order to compensate reactive power and to cancel current-type harmonics drawn by nonlinear loads connected to the same point of common coupling. A theoretical investigation that demonstrates the ability of such topology to compensate harmonics and limited reactive power is first presented. Then, the design and implementation of a linear quadratic regulator with integral action is presented. The converter is controlled as a whole i.e., a multiple-input-multiple-output system, and uses an augmented model that was developed in the d-q frame. Experimental results obtained with a digital-signal-processor-based DS1103 controller and the converter operating at a 20-kHz switching frequency proved the effectiveness of the theoretical study and the high performance of the proposed control strategy in compensating load harmonics and limited reactive power.
