Sinrace Power Supply Technology (Shenzhen) Co., Ltd.

Today rapid development in electronic technology, more and more attention to power electronics has been paid, the upgrading of power technology which is more relevant to promote the development of electronic equipment and components. People's daily lives, whether or modern electronic warfare, power supply system as its power source, its status and importance of self-evident. The quality of the product of power, whether military or civilian, are similar foreign products there is a clear gap. Therefore, the use of advanced international standards, to learn advanced foreign technology, as soon as possible so that the quality of power supply products catch up with international advanced level, all in the power of our development and production of engineering and technical personnel imperative.

Production and in daily life, power is a large wide versatility of electronic products, almost in the electronic research, production, teaching and all departments must use the power, in other various industries and daily life, Power has also been widely used. Therefore, understanding the current system of standards related to the revision of the power and actively participate in the revision of the standard system for the promotion of the development of power technology to improve power quality, and enhance the power supply manufacturers comparability between products, for users provide a scientific measure of the merits of the unified power quality standards is essential. Meanwhile, the development of standards and norms for a unified power market provides a legally binding document.

International Electrotechnical Commission (IEC) has developed some of the power of standards such as DC-stable power supply standard: IEC478.1-1974 "e ;DC power output stability term "e; IEC478.2-1986 "e ;stable DC output power rating and performance "e; IEC478.3-1989 "e ;DC output power supply conducted EMI stable baseline level and measurement & quote; IEC478.4-1976 "e ;In addition to the DC output power stability test methods for radio interference from outside "e; IEC478.5-1993 "e ;stable DC output power reactor magnetic field component of the near-field measurements. "e; This set of standards promulgated earlier time, China has not issued the corresponding national standards. DC-stable power supply and the relevant standards for the electronics industry SJ2811.1-87 "e ;general purpose DC Stabilized power terms and definitions, performance, and ratings "e; SJ2811.2-87 "e ;Test Method for Universal Power DC stability "e; has been promulgated and implemented 13 years. For a long time, the two standards of research and production of the DC stable power supply has played a significant role.

International Electrotechnical Commission (IEC) issued in 1980, IEC686-80 "e ;AC power output stability, "e; the light of the standards of our national standard GB / T "e ;General Specification for AC power output stability "e; has been submitted for approval to complete the standard terminology, Technical requirements and test methods refer to the IEC686, in addition, in 1994, the former Ministry of Electronics Industry issued the electronic industry standard SJ/T10541-94 "e ;AC power supply interference general technical conditions "e; and SJ/T10542-94 "e; AC power supply interference test method "e;, the standard exchange of stability by the Power Institute of China Committee and the domestic supply of professional power production plants, clinics and institutions responsible for preparing the test, and the interference of the ordinary type of AC power supply technical requirements, environmental requirements and corresponding test methods, quality inspection rules so made detailed provisions. Since the implementation of the standard release, the exchange of power technology has been widely used.

Other standards, such as with IEC443-1974 "e ;Measurement of stable power supply "e; corresponding to China's electronic industry standard SJ/Z9035-87 "e ;measurement of stable power supply "e; and also has been applied within a certain range.

In recent years the rise of the switching power supply and uninterruptible power supply, China has also developed a corresponding national standards, such as GB/T14714-93 "e ;micro computer system switching power supply (SMPS)for general technical conditions "e;, GB/T14715-93 "e ;information technology equipment General technical requirements of uninterruptible power supply "e;, etc., in the relevant field of application is very extensive. Ministry of the original four-machine standards SJ1670-80 "e ;Power electronics terminology "e; has been 20 years ago, many of the interpretation of terminology have been produced with the contradiction between the existing standard, so this year, organized by Ministry of Information Industry of the standardized criteria was amended to retain some of the original criteria still apply in terms of the standard classification method was larger adjustment, the purpose of this amendment is to enhance the standard criteria of applicability, so we based on the modern power of the most commonly used classification of several types of power, given their own terms and definitions, common part of the separate chapter, chapter terms and definitions in the light of relevant international standards and national standards, the Standard reported this year to complete. Currently our military problems in power system more reliable power system status quo is low overall, poor maintainability, electromagnetic compatibility problems are more prominent, and can not achieve interoperability, interchangeability, etc., but there is no military power systems standards, which resulted in the production plant of the line is yes, the production of power products is not compatible and equipment, and the power of non-standardized, non-specialized, non-standardized, which has seriously affected the reliability of military equipment as a whole and its development. Therefore, in order and to improve the overall level of China's military power, military equipment from the fundamental solution to the common areas of the power system can not meet the readiness needs of the contradictions of military power as soon as possible to develop national standards system is imperative.
