摘要
本文论述了大功率高频开关电源的数字实现方法,对DSP控制的高频数字开关电源做了初步的研究,设计了输出为28V/215A的高频开关电源的主电路和控制电路。最后,本文利用MATLAB7.0对主电路进行了仿真,验证了所提出方法的可行性。
A digital control method of high-frequent switching power supply is presented in this paper. A research on digital control high frequent switching power supply is carded out based on DSP, then the main circuit and control circuit of 28V/215A high frequent switching power supply have been designed. Experimental results verify the feasibility of the proposed method.
