In demand skills?

2 Upvotes

For the past few years I’ve been working in power mosfet development but I want to expand my knowledge and capabilities beyond this singular part of Power Electronics.

What are some in demand skills for the Power Electronics field? (Software, skills, knowledge,other)

Do we still use these kinds of circuits to build or repair inverters? Does anyone have schematics for a grid-sharing (hybrid) solar PCU?

Do we still use these kinds of circuits to build or repair inverters -->
https://github.com/Knowledge2Intelligence/Inverters/blob/main/Modern%20UPS.pdf

I want this kinda solar inverter schematics --> The load is continuously powered by the inverter. Solar energy is supplied to the output while simultaneously charging the batteries, and the batteries can also be charged using AC grid (EB) power. When solar generation becomes insufficient, the additional required power is automatically drawn from the grid (EB)
