<p>PROBLEM TO BE SOLVED: To provide a power conversion circuit system suppressing a circulating current.SOLUTION: A power conversion circuit system 8 includes: a primary side power conversion circuit 20 having a primary side coil 41 connected to the connection points of a plurality of transistors; a secondary side power conversion circuit 30 of a similar configuration to the primary side power conversion circuit 20, having a secondary side coil 42 corresponding to the primary side coil 41; and a control circuit 50 for power transmission control between the primary side power conversion circuit 20 and the secondary side conversion circuit 30. The control circuit 50 performs feed-forward control to set an on-off ratio of a both-end voltage signal of the primary side coil or a both-end signal of the secondary side coil, when a both-end voltage waveform of the primary side coil 41 is different from a both-end voltage waveform of the secondary side coil 42, according to at least one of a voltage ratio variation and a phase symmetric variation of both waveforms.</p> |
