Quick question:
Is it possible to create AC, or even a ripple current with flat DC without using any sort of switch?
yep.

I'm sorry, could you also explain, or point me somewhere I could read up on how it's done?

only an idiot would use one of these instead of an inverter, what the fuck is your problem with switches?

I think they are prone to failure and have reliability problems in the real world.

Still very interesting.
So, no way to get an alternating current from DC using only inductors, capacitors, and resistors?

Do you actually have a TASK for what you are asking about? If so what are the input conditions?
The real world doesn't care what you think and has solved all common and most uncommon power conversion issues.
Rotary converters (exemplified by motor-generator welding machines) are tough, but they are noisy, power hungry. large and not much use to most people. Motor-generator setups were the only game in town for high power outputs until semiconductor design evolved.
Pic is a God-tier 800 ampere DC output Lincoln. (Their ratings were conservative!) Many businesses still use these monsters because they are nearly indestructible and can be run at duty cycles which would destroy a rectifier machine.
Doh, fat fingered...
Wouldn't pretty much any oscillator circuit do it? What about an LC tank?

You would probably be a rich man if you invented a wave generator from a DC source with passive components.
