基于 TMS320F2812 的光伏逆变器研究

摘要
随着世界经济的发展,人类对能源的需求提出了更多的要求,而
能源的紧缺问题也越来越受到人们的关注。因此,风能、太阳能等新
兴能源迅速发展。如何更好地对利用风能、太阳能等新能源的问题也
受到了人们的关注。而电力电子技术,特别是开关电源技术在新能源
的使用中得到了广泛的应用。
本文提出了一种基于全桥变换器的正弦波逆变电源的整体设计
方案。文章首先对系统设计中将使用到的 DC/DC 变换器,DC/AC 变
换器以及 PWM 控制技术在理论上进行了深入的研究。并讨论了数字
式 PID 控制算法的实现和在系统中的应用,还针对这种基于全桥变换
器的正弦波逆变器提出了一种用一个电压闭环来调节两个控制量的
PID 算法。
其次,文章设计了基于全桥变换器、全桥逆变器和以 DSP 为核
心的逆变电源控制电路,详细介绍了各相关电路模块的原理与结构。
在完成电路参数设计以后,通过使用 MATLAB/Simulink 软件对整个
系统进行了仿真分析。并对系统软件设计的思路与实现方法以及关键
程序的流程进行了介绍。
最后,通过系统的带载实验对整套系统软硬件设计的合理性进行
了验证。实验结果表明,本文设计的逆变电源硬件电路和软件系统是
成功的。

The Research on Photovoltaic Inverter
Based on TMS320F2812

Abstract
For the development of global economy, the demands to energy are
increasing day by day and the shortness of energy draws more attention
than any time before. This condition gives great opptunity to the
development of new energy, such as solar energy and wind energy. Power
electronic technology, especially power swithing technology, gets popular
in the utilization of new energy.
The es up with a full-package solution to convert solar power
into AC. This solution is based on the design of the full-bridge converter
and the full-bridge inverter. This paper first gives full analysis on the
theories of power switching technology, inverter technology and PWM
technology. And the theory and fulfillment of PID algorithm are
discussed in this paper. Especially for this solution, this es up
with a PID algorithm in which two variables are being controlled in one
close-loop.
Then, this paper gives the procedure to calculate the main circuit
parameters. The design of digital controlling circuit and assistant circuits,
such as MOSFET driving circuit and voltage protection circuit, are
introduced. Based on the parameters worked out, the paper gives the
simulation of whole system in Matlab/Simulink. This paper also
introduces the firmware desig
