In order to control the power factor on a single-phase grid connectable inverter, a novel control method with Hilbert transformer is presented in this paper. Using Hilbert transformer theory, the d-q transformation on singlephase utility line current and utility voltage can be realized, and active power and reactive power can be controlled separately without offset. The effectiveness of the proposed control method is verified by the computer simulator, and some significant characteristics are also shown in this paper.
