In an electrolytic capacitor-less inverter, source current harmonics are caused by LC-circuit resonance, and the source power factor deteriorates. Therefore, an inverter must reduce harmonics control without additional circuits. This paper proposes a source current control method to reduce source current harmonics in a three-phase to three-phase electrolytic capacitor-less inverter of a permanent magnet synchronous motor drive. The proposed method consists of a source current control using the full-state feedbacks of a LC-resonance state observer. The validity of the proposed method is confirmed through experimental results.
