随着信息社会的发展，用电设备对高质量电源的需求日益增多，数字控制以其诸多的优点正逐步成为电源领域的研究新热点之一。本文介绍了开关电源和DSP的发展及其主要特点，阐明了其研究的必要性和重要性。从主电路的拓扑结构和控制方式，分析了开关电源、PFC电路、软开关PWM电路的工作原理。结合任务书的要求，设计了一款的1200W(48V/25A)，以TI公司的TMS320F2812型DSP芯片为主芯片的100KHz高频直流开关电源。采用两级变换方式，前级为升压式PFC变换器，后级为移相全桥软开关PWM变换器。
本文还分析和设计了驱动电路、采样电路、浪涌抑制电路和EMI滤波器，进行了MATLAB仿真。

With the development of information society, high-quality electrical equipment on the growing demand for power, digital control of its many advantages is gradually becoming the new research in the field of power one of the hot spots. In this paper, switching power supply and the development of DSP and its main features, elaborated on his study of the necessity and importance. From the main circuit topology and control, analysis of the switching power supply, PFC circuit, soft-switching PWM circuit works. With the requirements of the mission, the design of a 1200 W (48V/25A), to TI's TMS320F2812 DSP chip-chip-based high-frequency 100 KHz DC switching power supply. Transform used two methods, the former level for Boost PFC converter, for after-class full-bridge phase-shift soft-switching PWM converter.
It also analysis and design of the drive circuit, the sampling circuit, surge suppression circuits and EMI filter, a MATLAB simulation.
