PROBLEM TO BE SOLVED: To provide a charge circuit for a railway vehicle capable of improving the charge efficiency to an accumulator and besides permitting effective power consumption. SOLUTION: A charging circuit for the rolling stock, which is equipped with an axle generator 11 for performing power generation, according to the revolution of the axle of the rolling stock, being mounted on the rolling stock, a rectifying means 12 for rectifying the voltage generated by this axle generator 11, and an accumulator 15 for accumulating the voltage generated by the axle generator 11, and in which the axle generator 11, the rectifying means 12, and the accumulator 15 are connected, is equipped with a boosting means 13 which boosts the generated voltage to above the charge voltage by chopping control when the voltage generated in the axle generator 11 is lower than the charge voltage within the accumulator 15. |
