摘　　要：随着光伏应用规模的扩大,微电网逆变器的研究也逐渐被重视。提出了一种基于EG8010的单相逆变器设计方案。选择以SPWM单极性全桥电路实现逆变,再经过LC滤波,输出50Hz的标准正弦波。同时本设计还具备电压反馈、过流保护、过压保护功能。通过测试,当单相逆变器输入直流电压43V时,输出交流电压30V,交流电流1A,此时效率可达到87.83%±0.53%,负载调整率可达到0.46%±0.04%。With the expansion of photovoltaic applications,research on microgrid inverters is gradually being valued.This article pro-poses a single-phase inverter design scheme based on EG8010,choose to use SPWM unipolar full bridge circuit for inverter,and then undergo LC filtering to output a standard sine wave of 50Hz.At the same time,this design also has functions such as voltage feedback,over-current protection,and over-voltage protection.Through testing,when the single-phase inverter inputs a DC voltage of 43V and outputs an AC voltage of 30V and an AC current of 1A,the efficiency can reach 87.83%±0.53%,and the load adjust-ment rate can reach 0.46%±0.04%.
