Abstract As the power density of high frequency high power switched-mode power supply increases continuously, reasonable thermal design becomes a prerequisite to ensure the reliability of power supply. This paper presents a general thermal design method and describes how to design fans and heatsinks in detail. In order to optimize the structure of the power supply, the thermal field in the power supply is simulated by FLOTHERM. The practicality of the proposed design method is verified by a 15V/2kA high-frequency switched-mode power supply in the paper.
