Section 4 – Power Transformer Design - Texas Instruments

www.ti.com

Losses and Temperature Rise Transformer loss is sometimes limited directly by the need to achieve a required overall power supply efficiency. More often, transformer losses are limited by a maximum “hot spot” temperature rise at the core surface inside the center of the windings. Tempera-ture rise (°C) equals thermal resistance (°C/Watt)
