摘要
提出一种光伏发电技术应用在家用空调器的设计思想。对太阳电池的输出特性进行研究。在太阳能转移的过程中,系统用到最大功率点跟踪的方法,提高了系统的光伏发电效率。光伏阵列的输出电流进入Buck-Boost变换器,而后通过逆变器变为与电网电压同频、同相的交流电给空调供电。详细分析主电路的工作原理以及MPPT的跟踪原理,转换效率。仿真结果验证了理论分析的正确性。
A new design idea for photovoltaic technology applied in air-condition is presented. Output characteristic of so lar panel has been studied. When solar energy transfer, the method of Maximal Power Point Tracking（MPPT） is used, this method enhances PV efficiency. The output current from solar array enter into Buck-Boost converter, then become alternating current which has the same frequency and phase with grid via inverter, which can supply electricity for air-condition. The main circuit principle and tracking principle of MPPT are analyzed particular. The theoretical predictions are verified with the simulation results.
