Power technology has now been widely used in various fields of production and people’s lives, people’s production and life had a great impact on power technology started early, in its long course of development, the formation of different principles. characteristics a variety of different power technology. and now the two most widely used are the linear power supply and switching power supplies. With the development of industry, the industry is gradually to power. efficient power supply of direction, but because of its unique switching power supply switching characteristics and use it to meet the development needs of the power industry. has been great in the industry application. In this paper, high power high efficiency, digital as the premise, the use of embedded technology for the analysis and design of switching power supply. this paper do the following work:the topic needs to analyze the design, function and indicators proposed switching power supply, switching power analysis functions of each part of the different control modes. switch selection, inverter topologies are analyzed and compared. Ultimately choose the most studied switching power supply solutions.The switching power supply according to the function is divided into two parts:the main circuit. control circuit, main circuit analysis workflow to complete the selection process used by the power of each element of each original performance analysis calculations. The control circuit section is divided into a plurality of functional modules according to the different functions. the function of each module will be discussed. to achieve specific hardware circuitThis paper ARM processor core. compared to8.16-bit processor.32-bit processor is faster, more abundant hardware resources. low power consumption. good anti-jamming capability. Power functions will be brought into full play, system scalability, better human-computer interaction. the latter easier maintenance, system upgrades easier. based on the above considerations, software design, modular design, greatly simplifying the software design process.Paper-depth understanding of the literature and analysis of digital switching power supplies introduces the concepts, principles, characteristics and development direction, to provide a theoretical basis for further study of switching power supply.
