Abstract
A voltage detection device that is connected to a DC circuit to which a DC voltage is applied and that detects the DC voltage applied to the DC circuit includes a voltage conversion unit for outputting a first voltage that increases as the DC voltage increases and a second voltage that decreases as the DC voltage increases, an error detection unit for detecting an error for the first voltage and the second voltage based upon the first voltage and the second voltage when the DC voltage is, and a voltage calculation unit for correcting a difference between the first voltage and the second voltage based upon the error detected by the error detection unit and calculating the DC voltage based upon the corrected difference between the first voltage and the second voltage.
