Abstract
The voltage detection apparatus includes a reference power supply that outputs a predetermined voltage; a voltage conversion unit that converts detected information into a voltage; and a switching unit that switches between a first state in which the predetermined voltage is supplied from the reference power supply to the primary side of a transmission unit, and a second state in which the voltage resulting from the conversion is supplied from the voltage conversion unit to the primary side of the transmission unit. The switching unit switches to the first state, in which a correction value for correcting a digital value is acquired. The switching unit switches to the second state, in which a voltage value acquired based on the digital value is corrected with the correction value to acquire a corrected voltage value.
