The invention relates to a cooling structure of a vehicle drive inverter and a control system of the same. A cooling structure of a vehicle drive inverter includes: a switching element disposed in thevehicle drive inverter; a heat dissipation fin connected to and heat-exchangeable with the switching element; a cooling flow path in which a coolant flows and heat-exchanges with the heat dissipationfin; and an auxiliary cooling module connected to and heat-exchangeable with the switching element to be heated by a heat generation of the switching element or to be cooled together with the switching element.
