摘　　要：该文从理论上分析了采用太阳自动跟踪控制装置可提高太阳转换效率的空间 ;并阐述了采用不同于传感器方式的定时跟踪法的电路实现原理。这种电路不仅省去传感器和相关电路的能耗 ,更重要的是在该电路中可以实现最省电的休眠工作模式 ,使采用太阳自动跟踪控制装置后提高转换电能成为现实。该文还对比了固定安置的太阳电池板和采用了太阳自动跟踪控制装置的太阳电池板在相同条件下的转换效率。The conversion efficiency of solar energy to electric energy can be improved by using the device of automatic tracing sun in photovoltaic power system.The improving of PV efficiency conversion using the device of automatic tracing sun was calculated The principle of various sensors and the circuits for tracing sun device in which the energy dissipation was eliminated. The energy dissipation of the device would be less than the increasing electric energy as the device use.The conversion efficiency of solar energy to electric energy was tested for the fixed PV panel and the panel with automatic timing trace solar device under the same testing conditions,which confirms the great inhcreasing efficiency conversion by using the automatic timing trace sun device.
