Systems and method for selecting circuit element values for a hybrid active power filter operating over a variable frequency

摘要: Embodiments relate to systems and methods for selecting circuit element values a hybrid active power filter operating over variable frequency. In aspects, (HAPF) can eliminate current harmonics present in an AC source which are caused by load network.- implementations, the voltage - may be having frequency range, instance 360 800 Hz. Since encompass significant simple determination of correct or desirable capacitive inductive elements filtering section HAPF not possible. According analytic techniques provided allow those derived from impedance other provide satisfactory suppression identified harmonics, include 5 th , 7 11 13 17 19 23 rd 25 output voltage.
