Application of CNC DC regulated power supply
Power technology, especially CNC power technology, is a highly practical engineering technology that serves various industries. Power electronics technology is one of the best application technologies for electrical energy. Today's power technology integrates many disciplines such as electrical, electronic, system integration, control theory, and materials. With the development of computer and communication technology, the modern information technology revolution has provided broad prospects for the development of power electronics technology, while also placing higher demands on power sources. With the widespread use of CNC power supplies in electronic devices, the errors generated by ordinary power supplies during operation can affect the accuracy of the entire system. Power supplies can cause many adverse consequences during use, and countries around the world have put forward different requirements for power products and established a series of product accuracy standards. Only by meeting product standards can one enter the market. With the development of economic globalization, products that meet international standards can obtain entry and exit permits. Numerical control power supply only truly developed in the 1980s, during which the theory of power electronics for the system began to be established. These theories provided a solid foundation for their later development. In the coming period, CNC power technology has made significant progress. However, its products have the disadvantages of not meeting the requirements for numerical control, low resolution, relatively low power density, and poor reliability. Therefore, the main development direction of CNC power supply is to continuously improve the above-mentioned shortcomings. The emergence of microcontroller technology and voltage conversion modules has provided favorable conditions for the development of precise CNC power supplies. With the continuous development of new transformation technologies and control theories, as well as the research and application of various types of specialized integrated circuits and digital signal processing devices, by the 1990s, CNC power supplies with a precision of 0.05V and a power density of 50W per cubic inch had emerged. In terms of composition, CNC power supply can be divided into three parts: components, main circuit, and control. At present, in the field of power electronic devices, almost all voltage is regulated by rotary switches, which have low regulation accuracy and often jump, making it difficult to use
