A novel control method on single phase grid connectable inverter with Hilbert transformer - single phase current control on d-q coordinate

摘要

In order to control the power factor on a single-phase grid connectable inverter, a novel control method with Hubert transformer is presented in this paper. Using Hubert transformer theory, the d-q transformation on single-phase 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.
