EN Present tendencies of evaluation current distortion compensation methods aim to work out such compensator (serial or parallel active filter) which would be able to realize real time compensation of current distortions. The assumed aim of parallel active filter work is dynamic compensation of differential current which is the difference between load current and reference current. Unfortunately, dynamics of every real power electronics current source, being essential part of parallel filter, is limited. Proposed idea of increasing dynamics of active filter depends on temporarily changing inductance of coil at the output of such current source. For improving EMC of filter this coil is powered via low-pass filter. The paper presents idea of such modified parallel power electronics active filter and investigation results of simulation model.
