在住宅光伏系统中，微型逆变器通常作为分布式逆变器的替代品，进行面板级别直流-交流电力转换。太阳能微型逆变器帮助最大限度地提高能源产量，并缓解与部分遮挡、污垢或单PV板故障相关的问题。

微型逆变器中有一个DC-DC转换器（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）。设施中所有微型逆变器产生的数据（包括电压、电流和功率）由集中器收集和记录，并发送到本地或远程监控接入点。

我们面向微型逆变器设计提供的解决方案和集成电路包括功率MOSFET、电流隔离和高压栅极驱动器、以及高压碳化硅（SiC）二极管。与高性能STM32微控制器结合之后，意法半导体可以提供一套专用外设以帮助实现复杂的功率转换控制算法。能源计量集成电路、以及无线与有线连接解决方案（包括多标准电力线通信（PLC）调制解调器）使该组合更加完整。
