Abstract

An AC/DC conversion circuit of a power conversion apparatus receives an AC signal and has a switching element. A voltage sensing circuit generates a voltage reference signal according to an AC voltage signal. A harmonic generation circuit generates a harmonic injection signal according to the voltage reference signal. A subtraction circuit of a maximum power tracking circuit outputs a first DC signal and a second DC signal according to the voltage reference signal. An arithmetic circuit outputs a reference signal. A current sensing circuit outputs a feedforward signal according to one phase of an AC current signal. A current control circuit outputs an error signal according to the reference signal and the feedforward signal. A pulse width modulation circuit outputs a control signal to control the switching element according to the error signal and the harmonic injection signal, so that an aerogenerator operates at the maximum power approximation line.
