Abstract: A temperature regulating device regulates temperature of the magnetic circuit component incorporated in a power converter and including a magnetic core and a coil wound around the magnetic core and includes a cooling device that cools the magnetic circuit component, a temperature estimation device that estimates a temperature of the magnetic circuit component, a target temperature determination device that determines a target temperature of the magnetic circuit component, at which a loss of the magnetic circuit component is lowered, based on a relationship between temperature and loss of the magnetic circuit component, and a cooling suppressor that, when the temperature of the magnetic circuit component estimated by the temperature estimation device is equal to or lower than a predetermined temperature lower than the target temperature, suppresses the cooling of the magnetic circuit component by the cooling device so that the temperature of the magnetic circuit component reaches the target temperature.
