<p><P>PROBLEM TO BE SOLVED: To provide a power supply system with improved stability of an operation mode that makes only one voltage conversion part in two voltage conversion parts execute voltage conversion operation, and to provide a vehicle provided with the same. <P>SOLUTION: A hysteresis characteristic part switches output of selection commands SEL1, SEL2, corresponding to state characteristics ST1 and ST2 that depend on a current selection state (history). Namely, the hysteresis characteristic part executes switching determination, corresponding to the state characteristic ST1 when the selection command SEL1 is being selected; while it executes switching determination corresponding to the state characteristic ST2, when the selection command SEL2 is being selected. When a charge/discharge voltage Vb1 drops beyond a switching threshold voltage Vth1 compared with a charge/discharge voltage Vb2, switching from the selection command SEL1 to the selection command SEL2 is executed (transition characteristic TR12). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
