  • Power conversion system for controlling harmonics
    Patent number: 9397549
    Abstract: A power conversion system for controlling harmonics, which uses the Fourier transform analysis to calculate the harmonics element of each current, and adds the harmonics compensation strategy into the control strategy of the DC-AC power converter so as to decrease the harmonics element generated from the actual current.
    Type: Grant
