With the rapid development of the society, the use of electronic products is becoming more and more extensive. As an important part of energy supply, the power supply module is used more and more in the whole electronic field. The development of the power module, from the previous switching power supply to the current module power supply, has experienced great technological progress. Now, the module power supply is moving toward a higher level of evolution, mainly reflected in the following aspects!
High power, high density. Now electronic product, communication technology and equipment, integration module, etc., are increasingly demanding on the volume of electronic components, from the previous of large objects, switching power supply to the current module power matchbox, smaller to the demand of the chip! This will require the module power to continue to reduce the volume, improve the efficiency, increase the power density and so on, and then make some balance according to the product, so as to adapt to the development of the product.
Low voltage high current. The integrated circuit, which is responsible for the main data processing of the functional modules, is responsible for the core power consumption of the whole product. As the working voltage of the modern microprocessor continues to drop, the voltage of the module power output is from 5V before, to the present 3.3V even to 1.8v! According to industry forecasts, the power output voltage will drop below 1.0V. This determines, to maintain a high performance of the microprocessor, the voltage drop, the requirements of the current will be greater than the original to a certain level! The person all know, for the power supply module, low voltage high current has always been the technical difficulties of the industry, its technology, electronic components, process quality requirements higher and higher. Epp also sees this trend in the industry, so it will continue to research and develop technology in order to develop better products!
Green power module requirements. In the 1980s, the computer and electronic field adopted the switching power supply, which led to the generation of computer power generation. Since then, switch power technology has entered the field of electronics and electrical equipment successively. With the popularization of electronic products, the world's demand for energy is also on the rise. Ubiquitous electronic products, all kinds of new substitute for more traditional operation mode of equipment, even is like fire in the development of new energy vehicles, are from other energy supply mode into the demand for electricity, it will be terrible. To ensure the sustainable development of the industry, it means that green electricity will be the mainstream of the industry. Green computer refers to harmless to the environment, personal computers and related products green power refers to the green computer related efficiently save electricity power supply, according to the U.S. environmental protection agency l992 "energy star" on June 17, plan, desktop PC or related peripheral equipment, the power consumption in the sleep state if less than 30 watts, accord with the requirement of green computer, the basic way to improve the power efficiency is to reduce the power consumption. The power supply itself consumes 50 watts of energy for the current 200 watt switching power supply. Therefore, the green module power supply is a very important link for the entire human race!
Use software to design power supplies. Nowadays communication system, the increasing varieties of dc voltage, power density and the improvement of integration also increased the difficulty of design, we have always used the traditional manual design and verification, in the more complex system of product research and development have been unable to adapt to rapidly changing market demand, so the power aided design software arises at the historic moment.
Continuous acceleration of product update features! Above all, the development of the power module is also in the orbit of acceleration. The constant development of the external requirements, to facilitate the module power supply to a faster rate of replacement. For the power module enterprise, is not a small strength test!
