METHOD FOR DC ACTIVE FILTER CONTROL WITH PARALLEL CONNECTION OF VOLTAGE INVERTOR

摘要

A method for DC active filter control with parallel connection of a voltage inverter consists in measurement of pulsation voltage on an amplifier output, voltage and current in a parallel branch of filter and voltage of series branch is calculated, complex resistance of all filter branches for i-th harmonic and output inverter compensation voltage forfrequency of i-th harmonic are calculated according to the definite formulas.
