Transformers for power applications often are limited in size by an acceptable temperature rise. An acceptable temperature rise of a transformer is usually dependent on limitations of the materials ...
Soft magnetic materials (materials that can easily be magnetized) come in many forms. For switchmode power supply flyback transformers and chokes, we would consider gapped ferrites, Iron powder, ...
Power supply designers can increase efficiency while moving to a higher switching frequency. To prove this, engineers at Power Integrations tested comparable flyback designs running at 66 and 132 kHz.
