220V AC power enters the EMI (Transient Filter Circuit), first passing through the primary EMI (comprising capacitors and ferrite inductors), and then through the secondary EMI (consisting of MOV resistors, ferrite coils, and fuse tubes). High-frequency and pulse interference in the current are filtered out by the "x" capacitor (metalized polyester capacitor), resulting in an AC current with no peaks and low voltage. Aeronautical Power Supply
Low-voltage AC current enters the rectifying circuit, flows through the rectifier bridge (comprised of four diodes or a single component), and is rectified, resulting in a unidirectional pulsating DC voltage, known as pulsating voltage.
Pulse voltage flows into the main capacitor, passing through polyester capacitors and ceramic capacitors to filter out high-frequency and pulse interference. It then flows through the main capacitor to prevent interference, resulting in a direct current with voltage fluctuations, known as ripple DC.
The alternating current with ripples is first passed through a transformer to the secondary side, where it undergoes voltage stabilization before entering. It is then stabilized and rectified through a secondary side voltage stabilization IC chip, voltage diodes, and a high-power Schottky rectifier bridge. After passing through polyester capacitors for filtering, a pure low-voltage DC power supply is obtained. 400HZ power supply.
