PROBLEM TO BE SOLVED: To provide a circuit in which the number of ports in a primary side conversion circuit or a secondary side conversion circuit is increased more than the conventional ones without adding a new semiconductor element.SOLUTION: A power conversion circuit system includes: a power conversion circuit 12 including a primary side conversion circuit having switching transistors S1-S4 and a primary side coil Tr1 of a transformer and a secondary side conversion circuit having switching transistors S5-S8 and a secondary side coil Tr2 of the transformer; and a control circuit 10. Reactors L1, L2 and a coupling port D are connected between connection points of the switching transistors S1, S2 and connection points of the switching transistors S3, S4 in the primary side conversion circuit.SELECTED DRAWING: Figure 1 |
