Abstract
A power conversion system including a plurality of power conversion devices connected in parallel. Each of the plurality of power conversion devices includes: a power conversion circuit configured to convert DC to AC; and an AC filter circuit connected to an output side of the power conversion circuit. The AC filter circuit is an LC low-pass filter including a first filter reactor and an AC filter capacitor connected in an L shape. The AC filter circuit further includes a second filter reactor connected in series to the AC filter capacitor, and a resistance constructing a series circuit together with the AC filter capacitor and the second filter reactor.
