A DC power supply is a device that maintains a constant current in the circuit. Such as dry batteries, storage batteries, DC generators, etc.
The DC power supply has two positive and negative electrodes. The potential of the positive electrode is high and the potential of the negative electrode is low. When the two electrodes are connected to the circuit, a constant potential difference can be maintained between the two ends of the circuit, thereby forming a positive electrode to an external circuit. Negative current.
The difference in water level alone cannot maintain a stable water flow, and the constant water level can be maintained by forming a stable water flow with the help of a pump that continuously sends water from a low place to a high place. Similarly, the electrostatic field generated by the charge alone cannot maintain a stable current. With the help of a DC power supply, non-static action (referred to as "non-static force") can be used to make the positive charge from the negative electrode with a lower potential. The power source returns to the positive electrode with a higher potential to maintain the potential difference between the two electrodes, thereby forming a stable current. Therefore, a DC power supply is an energy conversion device that converts other forms of energy into electrical energy supply circuits to maintain a steady flow of current.

DC stabilized power supply gives you good-looking, I believe it will surprise you.
The rapid development of electronic technology has put forward higher requirements on electronic instruments and equipment: more secure and reliable in performance; increasing in function; increasing degree of automation in use; and increasing miniaturization in size. DC stabilized power supplies have developed rapidly in recent years due to their high efficiency, small size, and light weight. The high frequency of the DC stabilized power supply is its development direction. The high frequency reduces the size of the switching power supply and allows the DC stabilized power supply to enter a wider range of applications, especially in the high-tech field. Miniaturization and lightweight.
