<P>PROBLEM TO BE SOLVED: To improve the practicality of a power supply system for a vehicle mounted on the vehicle, which is provided with an electromagnetic suspension device arranged between the upper part and lower part of a spring. <P>SOLUTION: In this power supply system, when the terminal voltage of an electromagnetic motor 54 that the electromagnetic suspension device has is not more than a first threshold voltage E<SB>1</SB>(48V) higher than a set voltage E<SB>D</SB>(46V), which is a voltage driving the electromagnetic motor 54, that is, when the electromagnetic motor 54 requires power, the power is supplied by depressing the electric discharge voltage of a first battery 100 with a first converter 102 from the first battery, which is regarded as a nominal voltage E<SB>N1</SB>(288V) higher than the set voltage E<SB>D</SB>thereby feeding power. When the power is generated with the electromagnetic motor 54 when the terminal voltage of the motor 54 exceeds the first threshold voltage E<SB>1</SB>, the generated power is regenerated to a second battery 120, which is regarded as a nominal voltage E<SB>N2</SB>(12V) lower than the set voltage E<SB>D</SB>via a second converter 122. <P>COPYRIGHT: (C)2010,JPO&INPIT |
