In residential photovoltaic systems Micro inverters are often used as an alternative to string inverters to perform the DC to AC power conversion at panel level helping maximize energy yield and mitigate problems related to partial shading, dirt or single panel failures. In a micro inverter there is a DC-DC converter - implementing Maximum Power Point Tracking (MPPT) - and a DC-AC inverter to shape current and voltage for injection into the AC grid. Data – including voltage, current and power generated - from all the micro inverters in the installation are collected by a concentrator and dispatched to a local or remote monitoring and control access point.
Our solution includes MDMESH power MOSFETs, high-voltage, galvanically isolated gate drivers, high-voltage silicon-carbide (SiC) diodes together with high-performance STM32 microcontrollers - providing a set of dedicated peripherals to help implement complex power conversion control algorithms. Metering ICs and a range of wireless and wired connectivity solutions including multi-standard Power line modems complete the solution.
