SpletIn this paper, series notch filter (SNF) and decoupled band pass filter (DBPF) are proposed as adaptive filters. This subsection discusses theoretical analysis of proposed filters to eliminate voltage fluctuation that occurs in the dc-link capacitor described in Section 2, and improve PF of the input side. SpletSwitched capacitor circuits use capacitors and switches to emulate the behavior of resistors. Additionally, the frequency response is determined by the ratio of the capacitors, so even low frequency filters can be easily realized on-chip.
