Abstract
An MMC converter includes three units of two-terminal arms on a P-terminal side, and three units of two-terminal arms on an N-terminal side. An inductive element between the arms on the P-terminal side and the arms on the N-terminal side includes a reactor provided with a UP coil and a UN coil concentrically wound around an iron-core leg, a reactor provided with a VP coil and a VN coil concentrically wound around an iron-core leg, and a reactor provided with a WP coil and a WN coil concentrically wound around an iron-core leg. Each of the coils is wound around in a direction such that the iron-core legs are excited by a flow-through current from the N terminal to the P terminal.
