Would is be possible to use something like a Colpitts oscillator to drive an amplifier that is fed rectified input from the mains so that one can generate a higher frequency output that can be used with smaller transformers and inductors?
AD
It is certainly possible to use an oscillator to make a higher frequency power output i.e. such as 400Hz but the design of the power output devices and transformer is not for the novice.

Yes. Was done way back in the late 50s with a large (originally Public Address Amplifier) to provide 2kHz 110 volt power at about 2 kilowatts for a guided missile electronic test rig. Because the missile had a turbine driven alternator when in flight that was not available when ground testing the assembly.
Amplifier stood in a 2m high 48cm rack with 2 20cm high output tubes behind a glass window. Memory is getting foggy.

Thats half of how most modern switched modepower supplies work. The other half is monitor the V_out and adjust timing to give regulated output.

Yes, of course. It's "possible" to make almost anything. :-) What's your goal, and what's your budget? What style of oscillator you use is a whole field of study - the amplifier that uses the mains power to drive your loads is another.
What are you trying to accomplish?
Thanks, Rich
