Who has experience using solid-state frequency converters in aviation?

Who has experience using solid-state frequency converters in aviation? On-board reliability? I see more and more mentions of solid-state frequency converters in aircraft systems. Has anyone actually installed them on airplanes or UAVs? What are the weak points, if compared with generator units?

Drones usually use solid-state ones, 100+ hours of flight – no problems. The main thing is to monitor the cooling and EMI filters.

I haven’t installed such systems on board, but I have been interested in the topic for a long time and follow market trends. Solid-state frequency converters are increasingly used in aviation precisely because they have no mechanical parts, which improves reliability and reduces weight. For example, the 50hz website provides a fairly detailed description of solutions specifically for 400 Hz, including protection against overheating and power surges. If you are interested in more details, take a look at that page, which describes exactly such cases.
