The concept of main circuit design and its control strategy were provided. The fundamental features of this system are constructed by an constant voltage tracker to realize the maximum power output of PV array, a phase locker to make output current synchronous with main grid voltage. To avoid the“ island effect” and to identify the main grid is“ on” or “ off ” , over current or low voltage etc. ，some appropriate control sets are used in the system .In addition, the back feeds from the main grid to inverter was fully avoided by using soft phaselocking technology. Keywords: grid connected PV 。 DSP。 MPPT。 communication 0 引言日益恶化的生态环境使人们逐步认识到，人类必须走可持续发展的道路，大力开发和利用可再生能源是必由之路。太阳能光伏利用技术在这种形势下进入了快速发展的阶段。根据有关资料介绍：全球生产的太阳电池将有40%左右用于光伏并网发电。光伏电池发电有离网和并网两种工作方式，过去由于太阳电池的生产成本居高不下，光伏发电系统主要集中在中小功率的通讯、管网保护、交通信号和偏远无电地区的离网用户。随着...
