Abstract
A main circuit power feeder device for supplying control power from a main circuit power storage element to a main circuit control device includes: a plurality of voltage-division power storage elements connected in series; a voltage adjustment circuitry which is connected to the voltage-division power storage elements and adjusts voltages of the voltage-division power storage elements by mutual transfer of power among the voltage-division power storage elements; and a control circuitry which outputs control command values in two patterns that are a voltage-division control command value for dividing voltage of the main circuit power storage element among the voltage-division power storage elements and a bypass control command value for bypassing at least one voltage-division power storage element, in order to control the voltage adjustment circuitry, and which adjusts input voltage to the DC/DC converter.
