I want to drive a solenoid rated at 12V 1A. As you can see, the power demand is quite high. Can a solenoid be driven in PWM?
If so, what are some guidelines? IE: the minimum duty cycle to keep a solenoid active, etc.
Thanks ahead of time.

In my experience with solenoids, you may well need the 1 Amp initially to pull the core inwards, after that, the further in it gets the less current you`ll need, and Holding current when in the locked position can be significantly less than 1 Amp.
so you May be served well with a simple large value reservior capacitor for that initial hump.
I`v had solenoids that you`de be really hard pushed to pull apart when held with a simple watch battery when in the locked position.
might be worth experimenting with
