<p><P>PROBLEM TO BE SOLVED: To suppress variations in the voltage and current that accompanies the switching of operating modes. <P>SOLUTION: At switching of operating modes (primary voltage control mode, secondary voltage control mode and current-limiting mode) for a DC/DC converter 36, an I-term reconfiguration processing section 112 outputs an I-term corresponding to a drive duty in an operating mode, before switching to a PID processing section 110. The PID processing section 110 performs PID control based on the I-term input. As a result, the drive duty which is output, immediately after switching from a drive duty setting section 108 substantially equals the drive duty before switching; and as a result, continuity between the drive duties, before and after switching, is obtained. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
