In this paper, the current popular focus on a single chip switching power supply of low-power general-purpose switching power supply design and production. The choice of switching power supply a total of three major-TOP222 monolithic integrated circuit switching power supply, linear optocoupler PC817A and adjustable precision shunt regulator TL431. TOP222-chip switching power supply using the PWM duty cycle control switches to adjust the output voltage in order to achieve a stable output purposes.
The main contents of the completion of the design are: the need to choose according to the design of switching power supply circuit; design input rectifier filter circuit, and to identify the relevant device parameters; TOP222-based control of switching power supply for the core of the design; the design of high-frequency transformer, variable transformer determined than and the winding turns; the design of the output rectifier filter circuit, and to identify the relevant device parameters; design voltage feedback circuit; through the design of experiments and calculations to verify the data. Single-chip switching power supply integrated circuits with high integration, cost-effective, the most simple external circuit, the best performance index, can constitute a high-efficiency non-isolated power-frequency transformer switching power supply and so on. It was 90 years, the latter have come out in succession, they showed great vitality, it has become the current international development, low-power switching power supply, precision power supply and power switch of choice for integrated circuit modules. Posed by its switching power supply, in terms of cost with the same power supply linear regulator considerable, and significantly improve power efficiency, size and weight is greatly reduced. This new type of switching power supply for the promotion and spread, creating good conditions.

4.本人有1关于开关电源的英文论文
数字控制技术在开关电源中的应用正变得越来越广泛，开关电源的数字控制器通常包含三个主要的功能模块：模数转换器、数字补偿器和数字脉宽调制器。但随着开关频率的提高，常用的数字控制技术已逐渐不能满足开关电源在电能转换效率、静态及动态响应特性、复杂度、尺寸、重量，以及成本等方面的技术要求，从而降低了高频开关电源数字控制器的性能价格比，阻碍了其市场化进程。 本论文分析、比较了当今国际上先进的高频开关电源数字控制技术，重点分析了其模数转换器体系结构和数字补偿器，并在这两方面取得了创新性研究成果：指数量化的模数转换器结构和比例—前馈控制算法。 指数量化的模数转换器结构具有转换精度高、转换范围大、转换延迟低、结构简单、将转换结果压缩为查表寻址代码后所需的存储器尺寸小等优点。它可以增大电源输出电压的调节范围，改善数字控制器的控制性能，简化数字控制器的电路结构，从而可以提高其可靠性，并降低其成本。 比例—前馈控制算法能够提供非常好的输入调整特性，具有稳态性能好、瞬态响应快、算法复杂度低、计算延时小等优点。它可以改善数字控制器的控制性能，简化数字控制器的电路结构，从而可以降低数字控制器的成本。 。
【英文摘要】 Digital control technique is becoming more and more popular in the field of switching-mode power supplies (SMPSs). It usually consists of three key building blocks: analog-to-digital converter (ADC), digital compensator and digital pulse-width modulator. However, because of the increasing swithing frequency, conventional digital control technique can no longer satisfy the technical requirement of SMPSs, such as power conversion efficiency, static and dynamic response characteristics, complexity, size, weigh。
