  "textContent": "Embodiments to systems and methods for tuning the control of a shunt active power filter over a variable frequency. In aspects, a shunt active power filter is provided to filter current harmonics from the output delivered to a dc load via a recitifier. The shunt active power filter control can be configured as a set of resonant regulators connected in a parallel configuration. Each of the resonant regulators can be tuned to dampen or eliminate a particular harmonic, such as, the 5th, 7 th , 11 th , 13 th , 17 th , or 19 th harmonics. The shunt active power filter can be configured to target those or other harmonics over a range of source voltage frequencies, such as 360 - 800 Hz. The harmonics can be tuned over that or other source frequency ranges by determining the root locus poles of the filter as a function of feedback loop gain.",
