Izstrāde virziens of switch mode power supply technology
attīstība virziens of komutācija jauda padeve ir augsta frekvence, augsta uzticamība, zems patēriņš, zems troksnis, pretinterference un modularitāte. As switching power supply light, small, thin key technology is high-frequency, so the major foreign switching power supply manufacturers are apņēmies to the simultaneous development of new highly intelligent components, in particular, to improve the loss of the secondary taisngriezis daļas, and in the power ferrite (Mn Zn) materiāli to increase the science and technology **to improve the high frequency and larger flux density (Bs) to iegūt a augsts grāds of magnētisks veiktspēja, the And the miniaturizācija of kondensatori is also a key tehnoloģija.
High-frequency makes switching power supply miniaturisation, and switching power supply into a wider range of applications, especially in the field of high and new technology, promoting the miniaturisation of high-tech products, lightweight. In addition, the development and application of switching power supply has important significance in saving energy, saving resources and protecting the environment.
The application of SMT tehnoloģija ir padarīts liels progress in komutācija jauda padeve % 2c un komponenti ir sakārtoti abās pusēs no shēmas plāksnes lai nodrošinātu ka pārslēgšana jauda padeve ir gaisma % 2c mazs un plāns. Pārslēgšana barošana padeve of augsta frekvence būs neizbēgami ieslēgts tradicionālais PWM pārslēgšanās tehnoloģija uz realizācija of ZVS, ZCS soft switching technology ir ir mainstream technology of switching power supply, and ievērojami uzlabot efektivitāte of komutācija switching power supply, and ievērojami uzlabot efektivitāte of the switching power supply.
Modularitāte is the overall trend of the development of switching power supply, modular power supply can be use to form a distributed power supply system, can be designed as N +1} redundant power supply system, parallel mode capacity expansion. Komutācija barošana padeve darbība troksnis par šis trūkums, if the tiekšanās of augstfrekvence troksnis ir arī saistīts palielināt, un the use of part of the resonant conversion circuit technology, in theory, can achieve high-frekvences and can reduce the noise, but part of practical application of the resonant conversion technology is still a technical problem, it is still need to carry out a great deal of work in in šis lauks, in pasūtījums to make the technology to be practical.
nepārtraukta attīstība of power electronics technology, so that the switching power supply industry ir broad prospects for development. To speed up the development of China's switching power supply industry, it is need to take the road of technology **, out of the joint development of production, research and development of Chinese characteristics of the road, to contribute to comlight to the fast development of China's national ekonomika.
