摘要 基于dsPIC33FJ16GS504芯片,研制了一款微逆变器,设计了微逆变器的硬件结构及最大功率跟踪程序、负载均流程序、WIFI通信程序。经过对该微逆变器进行测试,证明其能稳定工作,能对单块光伏板进行最大功率点跟踪,且逆变器输出的谐波率和功率因数达到并网要求。 A micro-inverter based on dsPIC33FJ16GS504 is developed and the hardware construction, the MPPT, load balance and a WIFI communication program are designed. After being tested, it is proved that the micro inverter can work stably, track the maximum power point of the single board and the harmonic and power factor of inverter output meet the requirements of grid connection
