Low-voltage AC current enters the rectifying circuit, flows through the rectifier bridge (which can be composed of four diodes or a single component), and is corrected and rectified, producing a unidirectional pulsating DC voltage, also known as pulsating voltage.
2. The 220V AC power enters the EMI (Transient Filter Circuit), first passing through the primary EMI stage (comprising capacitors and ferrite inductors) and then the secondary EMI stage (consisting of MOV surge suppressors, ferrite coils, and fuses). It is filtered through an "X" capacitor (metalized polyester capacitor) to remove high-frequency and pulse interference from the current, resulting in a smooth, low-voltage AC output without sharp spikes.
3. The fluctuating direct current input to the transformer and secondary side is first stabilized within the transformer, followed by entering the secondary side where it is regulated and rectified by the secondary side's voltage regulator IC chip, voltage regulator diodes, and high-power Schottky rectifier bridges. The polyester capacitors then filter the output, ultimately providing a pure low-voltage direct current power supply.

4. The primary capacitive components of the pulsating voltage flow through polyester capacitors and ceramic capacitors to filter out high-frequency and pulse interference, pass through the main capacitor filter to prevent interference, and exit as DC with voltage fluctuations, known as ripple DC.
