Title: Power supply system and vehicle having the same
Inventor: ICHIKAWA SHINJI
IPC: B60L11/18
Filed: 2007-06-29
Abstract: Since maintaining a magnetic unsaturation until an inductor current (#Is), at which a core (CR1) is magnetically saturated, is reached, an inductor (L1) maintains an inductance value (Z1). As the inductor current increases beyond the value of #Is, the inductance value of the inductor (L1) decreases. On the other hand, an inductor (L2) maintains a magnetic unsaturation until an inductor current (Is) being reached and hence maintains an inductance value (Z2). Converters including the respective inductors (L1,L2) share supplying of power to a load apparatus, thereby reducing the loss related to a voltage conversion, while maintaining a transient stability.
