Abstract
A power conversion system including a single-phase AC power source for generating an AC power. The power conversion system further includes an AC/DC power converter connected to the single-phase AC power source for converting the AC power into a DC power, a main smoothing capacitor connected to DC terminals of the AC/DC power converter, a DC active filter connected in parallel with the main smoothing capacitor for controlling a compensation current flowing in the DC active filter such as to absorb an amount of fluctuation of the AC power supplied from the single-phase AC power source, and a load device connected to the main smoothing capacitor as a DC voltage source for receiving a first DC voltage applied to the main smoothing capacitor.
