<P>PROBLEM TO BE SOLVED: To provide a DC-DC converter and an interconnection system capable of fully improving its efficiency. <P>SOLUTION: The DC-DC converter 1 is equipped with a switching frequency decision section 8 which finds two or more inflection points from a curved line indicating the relationship between the entire loss of the DC-DC converter 1 and the frequency f of control signals s1, s2 for driving a conversion circuit 3, searches for the inflection point to reduce the loss to the least in two or more inflection points, and determines the frequency f corresponding to the searched inflection point as the frequency f of the control signals s1, s2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
