A20112 Power Supply Schematic ((new)) Jun 2026

Limits high inrush current when empty capacitors first charge.

As the magnetic field in the inductor completely collapses, these auxiliary windings generate a minor voltage drop signal. a20112 power supply schematic

Failure in the PFC stage often leads to the power supply being unable to handle full loads or failing to start due to Under-Voltage Lockout (UVLO) protections. Schematic Availability: Limits high inrush current when empty capacitors first
