“…In this context of adaptive filtering, two structures paid attention for its simplicity and previously applications in power conditioning [1], [19], [20]. The first filter is an adaptive notch filter structure that have been introduced by Widrow [21], for noise canceling.…”

“…11. This topology is able to compensate dynamically the system reactive power by controlling the APF voltage in order to adjust the power provided by the capacitor bank [18], [20]. The system set up is shown in Table IV. An appropriated control strategy based on the extraction of the harmonic contents is implemented in the DSP TMS320F2812.…”

This work presents a comparison between two adaptive filters applied to harmonic and reactive power detection in power electronics conditioners. The objective is to demonstrate their ability of tracking the signal variations without the use of synchronization techniques, with fast dynamic response and low computational burden. The algorithms are simulated and implemented in DSP TMS320F2812 for power electronics appliances. Important aspects concerning the computational efficiency, convergence speed, steady-state error are analyzed, in order to present the advantages of adaptive filters over the synchronous reference frame and algorithms dependents on PLL techniques.
