| Power electronics technology for the DC power supply provides a theoretical basis, and combination of electrical, electronic and control the three electrical engineering technology is an interdisciplinary applied technology. Its core is the power conversion and processing, its widely used in the production, research, teaching and other fields, is one of the most commonly used devices in electronic technology, is also an important part of most of the equipment and electronic instruments, power quality is good or bad. ability to adapt to the external environment directly affects the control systems, electronic devices, equipment performance, reliable operation of the machine, is an important factor.To distinguish between good or bad, of the power quality and adaptability to the external environment and so need to be science, feasibility, and reasonableness of the test. It can be said that the test is very important to power production processes.This paper first introduces the development status of the power and now two main type of power linear power supply and switching power supply; laboratory testing program with an important indicator of the DC power supply designed according to the characteristics of power; designed a performance optimization of the DC line power supply; and its simulation. |
