<P>PROBLEM TO BE SOLVED: To provide a power conversion circuit system capable of preferably charging secondary batteries connected to each of a primary conversion circuit and a secondary conversion circuit by using an external AC power supply. <P>SOLUTION: A power conversion circuit system 101 includes two input-output ports of a primary conversion circuit 20 and two input-output ports of a secondary conversion circuit 30 magnetically coupled to the primary conversion circuit 20, that is, four input-output ports in total. The power conversion circuit system 101 has: a secondary battery 55 connected to any one of input-output ports of the primary conversion circuit 20; a secondary battery 60 connected to any one of input-output ports of the secondary conversion circuit 30; an external AC power supply 78 connected to any one of the four input-output ports; and a control circuit 50 performing control so that at least one of the secondary battery 55 and the secondary battery 60 is charged with power input from the external AC power supply 78. <P>COPYRIGHT: (C)2012,JPO&INPIT |
