Claim Text:
1. An electric power conversion system comprising: a primary conversion circuit comprising a primary coil, a primary magnetic coupling reactor, a primary positive electrode bus, a primary negative electrode bus, and a primary bypass circuit; a secondary conversion circuit comprising a secondary coil, a secondary magnetic coupling reactor, a secondary positive electrode bus, a secondary negative electrode bus, and a secondary bypass circuit; a first input/output port provided between the primary positive electrode bus and the primary negative electrode bus; a second input/output port provided between the primary negative electrode bus and a center tap of the primary coil; a third input/output port provided between the secondary positive electrode bus and the secondary negative electrode bus; and a fourth input/output port provided between the secondary negative electrode bus and a center tap of the secondary coil, wherein the primary bypass circuit is configured to short-circuit one end of the primary coil of the primary conversion circuit to another end of the primary coil, and wherein the secondary bypass circuit is configured to short-circuit one end of the secondary coil of the secondary conversion circuit to another end of the secondary coil.
