Abstract: There is provided a voltage drop simulation device including: a memory; and a processor coupled to the memory and the processor configured to: divide a conductive body in which a current to be supplied from a power source to elements arranged on a PCB flows into a plurality of meshes including at least one mesh whose size is different from other meshes, calculate voltage values of a plurality of measurement points set in the plurality of meshes, respectively, and calculate a voltage drop of each of the plurality of meshes by dividing, for each of the plurality of meshes treated as a target mesh, a difference between voltage values of a first measurement point included in the target mesh and a second measurement point included in an adjacent mesh that is adjacent to the target mesh by a distance between the first and second measurement points.

Abstract: The present invention is intended to prevent the flow of a large input current into a DC/DC converter, to which power is fed from a power supply, before a supply voltage delivered from the power supply reaches a rated output voltage. A control unit included in the DC/DC converter includes a steady state detection block that detects a condition in which an input voltage to be applied to the DC/DC converter has been stabilized, and inhibits the power feed from the DC/DC converter until the input voltage delivered from a power supply in a preceding stage is stabilized.

Abstract: A tertiary coil is provided in a DC/DC converter. An electric current is generated in the tertiary coil due to on an alternating-current voltage produced in the tertiary coil. An electrical current supplying circuit supplies the electric current generated in the tertiary coil to a load when supplementary power must be supplied to the load.
