Power densities and power supply components have improved such that the major obstacle in using DC-DC converters is effectively removing the heat from these devices. This paper shows practical and theoretical heat removal issues through conduction, natural convection and forced air convection. Thermal resistance and its applications are discussed. Thermal derating and how it applies to the converter is also discussed.
