In this paper, a new topology for a shunt active power filter using a matrix converter is proposed. The topology analysis, description of the associated control technique, steady-state and dynamic performance are also presented in this study. The proposed topology does not contain the bulky DC-link capacitor. In addition, the parameters of the proposed filter are robust against the change in the load and the THD percentage is the same under this condition. So, the proposed filter parameters do not require to be retuned with load change. Moreover, a simple and compact form can be realised. The reference currents are calculated using a synchronous reference frame theory. Space vector modulation and hysteresis current control are used to control the rectifier and inverter stages in the indirect matrix converter to obtain the required injected filter current. Finally, a simulation model and an experimental prototype are implemented using Matlab/Simulink program and DSP1104, respectively, with a detailed analysis to the obtained results which confirm the effectiveness and the high accuracy performance of the proposed topology.

In this article, different matrix converter (MC) control strategies are comprehensively explained. Further, an ultra-modified space vector modulation (UMSVM) of the MC is proposed. The total harmonic distortion for both output voltage and current is reduced, when the proposed UMSVM technique is applied. Moreover, a modified indirect space vector modulation with feed forward controller (MISVMFC) of the MC is also proposed in order to obtain a fixed output voltage and frequency for different wind speeds. The advantages of the MC are introduced in this article. These advantages include the wide range of the output frequency of MC, which may be greater than the input frequency and the control of both the output voltage magnitude and input displacement factor (IDF). Extensive theoretical and simulation results about conventional and proposed control techniques for the MC are presented. Experimental test bench is constructed and several experimental results are obtained. The experimental results validate the simulation ones. [ABSTRACT FROM AUTHOR]
