By approximation method analyzed the main circuit device power losses of milling machine converter, calculated the main components’ loss, and on this basis, designed cooling device of milling machine traction converter for ensuring the power device operating in the junction temperature range. The experiments proved that the cooling device realized the heat dissipation function, the main power device achieved the cooling effect, thereby protecting the power device, and ensured the stable operation of the locomotive.
