摘　　要：文章介绍了作者研制的太阳能发电系统,该系统由光伏电池、蓄电池、逆变器、数据采集板、上位机等几部分组成.对该系统各部分的功能和相互联系进行了分析,其中逆变器的电路结构与目前常用的结构不同,所以文中重点叙述逆变器的设计,包括电路结构、DSP软件的流程图、PWM波形的产生原理.该系统在实验室运行稳定可靠,逆变器输出的交流电压正弦度好,谐波小,通过数据采集板和上位机可实时监测系统的运行状况.可为住宅光伏发电提供技术上的参考.A Photovoltaic Power System is introduced in this paper, which consists of solar battery arrays, storage batteries, inverter, data collection board and PC computer. Besides, each part＇s function and their interconnection are discussed. The unique design of inverter, including circuit structure, DSP software flow chart and PWM wave generation principle, is described in detail. The system works well in laboratory, with good sine waveform and little harmonics of AC voltage generated by the inverter, and the system＇s performance is monitored in real time by data collection board and PC computer. The research is expected to offer some technical support for photovoltaic power system.
