When the two electrodes are connected with the circuit, the potential difference between the two ends of the circuit can be kept constant, so that the potential difference between the two ends of the circuit in the external circuit Thereby forming a current from the positive electrode to the negative electrode. Water level alone can not maintain the level of the steady flow, and by means of water pumps continue to send water from low to high can maintain a certain level of water and the formation of a steady flow. Similarly, the electrostatic field generated by the charge alone can not maintain a constant current, and by means of a DC power supply, the non-electrostatic action (referred to as "non-electrostatic force") can be used to make the positive charge from the negative- The internal power back to the higher potential of the cathode to maintain the potential difference between the two electrodes to form a steady current. Therefore, the DC power supply is an energy conversion device that converts other forms of energy into a power supply circuit to maintain a constant current flow.
AC power supply can provide a stable voltage and frequency of the power supply, said AC stable power supply. At present, most manufacturers do the work of AC voltage stability. The following combination of market and some of the exchange of regulated power supply briefly its classification characteristics. The basic principle is the LC series resonance, the early emergence of the magnetic saturation regulator belongs to this category.It has the advantage of: the structure is simple, no number of components (resonant) type of power supply, , The reliability of a very high voltage range is quite wide, anti-interference and anti-overload capability. Disadvantages are: energy consumption, noise, bulky and high cost.
