Power Transformer
Grid-provided alternating current is typically 220V (or 380V). Various electronic products require different DC voltage ranges. Therefore, it is often necessary to first pass the grid voltage through a power transformer, then rectify, filter, and regulate the transformed secondary voltage to obtain the required DC voltage amplitude.
Two, Rectifier Circuit
The function of a rectifier circuit is to convert alternating current (AC) voltage, which alternates between positive and negative, into direct current (DC) voltage by utilizing rectifying elements with unidirectional conductivity. However, this unidirectional pulsating voltage often contains a significant pulsation component, and adjustable DC voltage regulators are still far from the ideal DC voltage.
Filter
The filter circuit is primarily composed of energy storage elements such as capacitors and inductors. Its main function is to filter out as much of the unidirectional pulsating AC component as possible, resulting in a relatively smooth DC voltage output. However, when the grid voltage or load current changes, the amplitude of the DC voltage output from the filter also varies. This is not acceptable in high-power DC power inverters for electronics with stringent requirements.

Four: Voltage Stabilization Circuit
The role of a voltage-regulating circuit is to take certain measures to prevent the aging of high-power DC voltage regulators, ensuring that the output DC voltage remains balanced when there are changes in grid voltage or load current. As we all know, simply relying on the static electric field generated by charge is not sufficient to maintain a constant current. Therefore, a programmable DC voltage regulator is used to utilize the force of non-static electricity to return the current from the negative pole back to the positive pole of potential, thus maintaining the potential difference between the two electrodes and forming a constant current.
