Reduce Iron Loss In Switching Power Supplies

Reduce 400 watt power supply iron loss

Use a core material with better 12v 33a power supply power dissipation parameters, such as TDK's PC50 instead of PC40.

This reduces magnetic flux density, but increases the number of coil turns, leading to increased 400w switching power supply copper loss. Use with caution.

Use wire with lower resistivity (not practical).
