Experimental and simulation approach of cooling system in 3-phase inverter using extended surface

Overheating is a failure mode that significantly affects the reliability of electronic devices. All devices, including 3-phase inverter driving traction motor, produce heat dissipation. Heat dissipation needs to be controlled with cooling prevent overheating. can avoided by increasing or reducing in caused internal resistance metal–oxide–semiconductor field-effect transistor (MOSFET), switching loss, and other factors. Cooling for use water coolant air coolant. The system based on amount produced. addition an extended surface area sink. sink uses aluminum material, often called pin fin. There are kinds available market. We calculated generation MOSFET's resistance, validated simulation results experimentally using thermal camera. Thus, we could find optimal number, dimensions, type fin inverter.
