POWER CONVERSION APPARATUS AND POWER CONVERSION METHOD

摘要

A power conversion apparatus includes: a primary side circuit; a secondary side circuit that is magnetically coupled to the primary side circuit by a transformer; and a control unit that adjusts a transmitted power transmitted between the primary side circuit and the secondary side circuit by changing a phase difference between a switching operation of the primary side circuit and a switching operation of the secondary side circuit such that a port voltage of one port from among a primary side port provided in the primary side circuit and a secondary side port provided in the secondary side circuit converges on a target voltage. The control unit reduces the target voltage when the phase difference is equal to an upper limit value and the port voltage is smaller than a set threshold.
