POWER CONVERTER

摘要

A power converter (1) is provided with: an electrical circuit (3) including a heat-generating source (31); a heat-pipe cooler (9) in which refrigerant is sealed, the heat-pipe cooler (9) cooling the heat-generating source (31); a frozen-determination means (25) for determining whether the refrigerant is frozen; and an output-limiting means (22) for limiting output when the frozen-determination means (25) determines that the refrigerant is frozen.
