针对目前光伏最大功率点跟踪(MPPT)技术研究和应用现状, 根据控制算法的不同分类, 选取固定电压法、扰动观
察法、增量电导法作为研究对象。分析各种控制算法的实现原理, 并且在反激式变换器上进行试验验证, 对试验结果进行比较
分析, 得出三种MPPT 控制方法在启动时间、动态响应、稳态控制精度等方面的性能, 本文最后提出一种在实际应用中能够达到良好控制效果的固定电压启动结合增量电导算法, 该算法动态响应快、稳态控制精度高。

围绕着如何提高石英晶体振荡器的频率稳定度，本文集中探讨了以下几个方面的工作：分析了石英谐振器的特性及其对晶体振荡器性能的影响，从而为高稳定度石英晶体振荡器中对石英晶体的选择提供了依据。分析了振荡电路基本原理，从而设计出由2N3904构成的石英晶体振荡电路，并对电路中输出电路部分及稳压部分设计中的问题进行讨论。最后，论述了恒温晶体振荡器的主要制作过程和技术指标，并对试制石英晶体振荡器样品技术性能进行了测试和分析。
Centered on how to improve the quartz crystal oscillator frequency stability, the paper focused on the following aspects of work: analysis of the quartz resonator and the characteristics of the performance of crystal oscillator, so as to the high degree of stability in the quartz crystal oscillator The crystal to provide the basis for the choice. Analysis of the basic tenets of oscillation circuit, designed by 2 N3904 posed by quartz crystal oscillator circuit, and circuits in output regulators and circuit design of some of the issues discussed. Finally, on a constant temperature crystal oscillator the main production process and technical indicators, and trial production of quartz crystal oscillator technical performance of samples were tested and analyzed.
