<p>[Problem] To provide a power conversion apparatus that easily eliminates fluctuations of output from solar cells and the like. [Solution] This power conversion apparatus is provided with: a DC link unit; a first transformer circuit for transforming direct-current voltages outputted from a direct current power supply into direct current voltages to the DC link unit; a second transformer circuit for direct-current direct current voltages in two ways between the direct current power supply and the DC link unit; a control unit, which determines direct-current operation quantities for respective transformer circuits, and on the basis of the operation quantities, controls direct-current operations of the circuits; an alternating current-side terminal having an alternating current power line connected thereto; an inverter circuit, which performs direct current to alternating current conversion of the voltages transmitted from the DC link unit to the alternating current-side terminal and/or alternating current to direct current conversion of the voltages transmitted from the alternating current-side terminal to the DC link unit. The control unit determines the operation direction and the operation quantity of the second transformer circuit using information of the operation quantity of the first transfer circuit.</p> |
