Resumen
This work presents the study and project of a single-phase parallel active filter, which is an equipment used to compensate the load harmonic currents, collaborating in the improvement of the power quality. An strategy of simplified control, which generates the reference current, is applied to this active filter. The study exposes a proposal to alterate the voltage loop control, through the addition of a low-pass filter in this structure to attenuate oscillations in the dc-bus of the voltage source inverter, enabling the increase of the speed of the control action of the voltage loop, resulting in a better dynamic response. Computational analysis and simulation results are demonstrated in order to validate the improvement in the dynamics of the active filter, making its dynamic behavior equivalent to the strategies of convencional control during the load transients.
