Abstract :
This paper presents a new control method of single-phase hybrid active power filter for the compensation of harmonic current components in nonlinear R-L load with passive filters. To construct two phase system, an imaginary second phase was made. In this proposed method, the new signal which is the delayed through the filtering by the phase-delay property of low-pass filter is used as the secondary phase. Because two-phases have the different phase, the instantaneous calculation of harmonic current is possible. In this paper, a reference voltage is created by multiplying the coefficient k by the compensation current using the rotating reference frame synchronized with the source-frequency, not applying to instantaneous reactive power theory which has been used with the existing fixed reference frames. To verify the validities of the proposed control methods, experiments are carried out for the prototype of single-phase hybrid active power filter system
