在住宅光伏系统中,微逆变器通常作为串型逆变器的替代品,进行面板级别直流-交流电力转换,有助于最大化能源产出,并可以缓解由于电池板部分遮挡、污垢或单板故障出现的问题。微型逆变器中有一个DC-DC变换器(实现最大功率点跟踪(MPPT)),以及一个DC-AC逆变器(对注入交流电网的电能进行电流和电压整形)。所有微型逆变器产生的数据(包括电压、电流和产生的功率)由集中器收集并发送到本地或远程监控接入点。

我们的解决方案包括MDMESH功率MOSFET、高压、(电)隔离栅极驱动器、高压碳化硅(SiC)二极管以及高性能STM32微控制器,提供一套专用外设以帮助实现复杂的功率转换控制算法。电能计量集成电路和一系列无线与有线连接解决方案(包括多标准电源线调制解调器)使解决方案更加完整。
