Abstract
A power conversion apparatus includes a transformer; a primary side full bridge circuit provided on a primary side of the transformer; a first port connected to the primary side full bridge circuit; a second port connected to a center tap of the primary side of the transformer; a secondary side full bridge circuit provided on a secondary side of the transformer; a third port connected to the secondary side full bridge circuit; and a control unit configured to cause an upper arm of the secondary side full bridge circuit to operate in an active region in a case where a capacitor connected to the third port is charged with a transmitted power transmitted to the secondary side full bridge circuit via the transformer from the primary side full bridge circuit when power of the second port is stepped up and the stepped up power is output to the first port.
