Can we develop here universal electronic switch which can swich DC or AC effectively at quite fast rate ? Something which can be used as replacement of triac and mosfet and mechanical switch for shortcircuit for example coils or transformer windings also.
Any ideas ?

I know it can be done using two mosfets: N and P but the devil is hidden in details how to make it work without a path to AC current to flow around via grounds. Maybe some optocouplers ?

Is it even possible to make such a switch ?

It's time to test if I can build it and use to shortcircuit coil.
