Power conversion device

A power conversion device comprising:

• a transformer to convert power in a state in which a primary side and a secondary side are insulated from each other;
• a first connection conductor to electrically connect together a primary winding of the transformer and a primary-side electronic component;
• a second connection conductor to electrically connect together a secondary winding of the transformer and a secondary-side electronic component;
• a first housing containing the primary-side electronic component and comprising a first opening part through which the first connection conductor is inserted;
• a second housing containing the secondary-side electronic component and comprising a second opening part through which the second connection conductor is inserted;
• and
• a third housing containing the transformer and comprising a surface in which an aperture is formed through which the first connection conductor and the second connection conductor are inserted, wherein
• an interior of the third housing is filled with an insulating member, and the insulating member in the interior of the third housing seals the transformer, a portion of the first connection conductor, and a portion of the second connection conductor,
• the first opening part and the second opening part are blocked by one surface, in which is formed the aperture, of the third housing filled with the insulating member,
• a shortest distance between an edge of the first opening part and the first connection conductor is greater than or equal to a first threshold, and a shortest distance between an edge of the second opening part and the second connection conductor is greater than or equal to a second threshold, and
• the third housing is disposed at a position such that at least a portion of an outer surface of the third housing contacts outside air.
