DIGITAL CONVERSION DEVICE AND POWER CONVERSION DEVICE

摘要

A digital conversion device that removes a pulse-shaped noise component without causing the delay in the obtained information, and a power conversion device that performs power conversion in which the digital conversion device is utilized. The digital conversion device includes: a plurality of information signal holding units (301 etc.) capable of inputting information signals with delay by a predetermined time, the information signals being indicative of a value varying momentarily, and holding the values at a time when each of the values is inputted; a removing unit (307) capable of removing a value farthest from the other values among the values held by the plurality of information signal holding units; an averaging unit (308) capable of averaging the values that are not removed by the removing unit; and a converter (309) capable of performing AD-conversion of a value outputted from the averaging unit and outputting an AD-converted value as digital information. The predetermined time has a value shorter than time required for the conversion to the digital information performed by the converter.
