Features and requirements of a DC voltage stabilized power supply unit
With the rapid development of power electronics technology, DC power supply is widely used, its good or bad directly affects the performance of electrical equipment or control system, DC regulated power supply has the following basic functions and requirements.
1, the output voltage value can be arbitrarily set below the rated output voltage value and normal operation.
2, the output current value of the current stabilizer can be arbitrarily set below the rated output current value and normal operation.
3, for the output voltage value and current value have precise requirements of DC regulated power supply, generally use multi-turn potentiometer and voltage and current trimmer potentiometer, or direct digital input.
4, to have a perfect protection circuit. DC regulated power supply should not be damaged when the output short circuit and abnormal working condition occurs, and can work normally immediately after the elimination of abnormal conditions.
5, DC regulated power supply voltage regulator and current regulator state can be automatically converted and have the corresponding state indication.
6, for the output voltage and current values require accurate display and identification.
DC regulated power supply in the power supply technology occupies a very important position, the commonly used DC regulated power supply requires stable voltage, reliable operation, sufficient power.
Prospect of DC regulated power supply
In recent years, with the development of science and technology, DC regulated power supply operating frequency of the original dozens of kilohertz to the current hundreds of kilohertz development, but there is still a certain gap with the developed countries in the West; led by the United States in this area of research in a number of developed countries has turned to high-frequency power supply under the theory of topology, principle of operation, modeling and analysis of the leading technology, etc.; therefore, the development and application of DC regulated power supplies in this regard And it also from in a big gap.
