dc-dc what is specific as follows:
A, Introduction
1, DC-DC converter (DC-DC converter) is a direct current circuit will be a voltage value of the electrical energy into another voltage value of the electrical energy device;
2, DC-DC is a newly developed miniaturized power switching module, it is the use of microelectronics technology, small surface-mounted integrated circuits and microelectronic components. /p>
2, DC-DC is a newly developed miniaturized power switching module, it is the use of microelectronics technology, small surface-mounted integrated circuits and microelectronic components assembled into one and constitute a DC-DC power module is conducive to simplify the power supply circuit design to shorten the development cycle, to achieve the best indicators, etc., can be widely used in various types of digital instrumentation and intelligent instrumentation;
< p>3, DC-DC power modules are widely used in power electronics, military, scientific research, industrial control equipment, communications equipment, instrumentation, switching equipment, access equipment, mobile communications, routers and other communications fields and industrial control, automotive electronics, aerospace and other fields;4, due to the use of modules to form a power supply system has a short design cycle, high reliability, easy to upgrade the system and other characteristics. The application of power modules is becoming more and more widespread. Especially in recent years due to the rapid development of data services and distributed power supply system continues to promote the increase in power modules has exceeded the primary power supply;
5, with the semiconductor process, packaging technology and high-frequency soft-switching large number of uses, power modules, power density is getting bigger and bigger, the conversion efficiency is getting higher and higher, the application of the more and more simple;
The second, functionality
1, noise isolation: (analog and digital circuit isolation, strong and weak signal isolation); security isolation: strong and weak power isolation \ IGBT isolation drive \ surge isolation protection \ lightning isolation protection (such as human contact with the isolation of the medical electronic equipment protection); ground loop elimination: remote signal transmission \ distributed power supply system;
2 ?€€?€€boost conversion\buck conversion\\ AC/DC, DC/AC\\ polarity conversion (positive and negative polarity conversion, single power supply and positive and negative power supply conversion, single power supply and multiple power supply conversion); short-circuit protection, over-voltage protection, under-voltage protection, over-current protection, and other protections; the use of active filtering; AC mains power supply\remote DC power supply\distributed power supply system\battery power supply.
