<p><P>PROBLEM TO BE SOLVED: To variably control the output voltage of a fuel battery system. <P>SOLUTION: Electric equipment 100 includes a first input terminal 102 which inputs the first DC supply voltage of the fuel battery system 200 having controllable supply voltage; a second input terminal 104 which inputs the second DC supply voltage of a chargeable secondary battery; a DC voltage conversion circuit 110 which inputs the first and second DC supply voltages from the first and second input terminals to supply required voltage current to a load; a charging circuit 120, which inputs the first DC supply voltage from the first input terminal to supply the charging DC supply voltage to the second input terminal; and a control circuit 140 which decides the required value of the first DC supply voltage, based on the value of the second DC supply voltage of the secondary battery for supplying the decided required value to the fuel battery system. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
