资料介绍

模拟控制的Boost-ZVT有源功率因数校正电路,其缺点是设计复杂,系统容易受元器件老化及受温漂影响而引起误差。针对这个问题,设计了一种基于DSP的全数字控制电路。首先介绍了Boost-ZVT电路的工作原理,对其主要元器件参数进行了设计,然后详细地阐述了基于TM320F2812的数字控制硬件电路设计。最后给出其实验结果,实验结果表明采用全数字控制不但能实现模拟控制的所有功能,而且能够显著降低系统的体积和重量,而且便于系统调试和升级。

For analog control Boost-ZVT active power factor correction circuit,its disadvantages are in the design complexity ,and the system is easy to be affected by the components of the aging and temperature drift to cause error. A full digital control circuit based on DSP is designed to solve this problem. Firstly,the working principle of Boost-ZVT circuit is introduced,and the parameters of the main components are designed,and then the hardware circuit design of digital control based on TM320F2812 is described in detail. Finally,the experiment results are gave,and the experimental results show that the full digital control can not only realize the simulation control of all functions,but also can significantly reduce the volume...
