Title:
Power converter
Document Type and Number:
Japanese Patent JP6038289
Kind Code:
B2
Abstract:
A power conversion device includes: a DC current calculation unit (50) for calculating a circulating current component (izuc, izvc, izwc) for each phase which circulates between the phases through first arms (18) and/or second arms (20) not via an AC power supply (14) and a DC power supply (16); and a circulating current control unit (52) for controlling the circulating current component (izuc, izvc, izwc) for each phase so as to follow a predetermined circulating current command value (izuc*, izvc*, izwc*), thereby reliably suppressing variation in voltages of DC capacitors of unit cells (10) among the phases even in such a case where an impedance (15) is additionally inserted in a DC circuit.
