Converters operation

Hello there,

I am a starting learner of power electronics.
I have a small question which is bothering me. It is probably silly for most people experienced with power electronics.
Do converters work with an input voltage that varies?
For example: A boost converter that gives an output of lets say 48V, would it work if the input voltage may be changing from 3V up to 5V?

Thank you for the help in advance!

Yes most of the boost converters have a wide input voltage range to convert from, there will be a Minimum input to get your desired output voltage, check the datasheet of the chip you want to use.

There are also transient conditions over and above the initial selection of an input voltage. For example a very slow transient would be the discharge of a battery. A very fast transient would be a spike caused by capacitative or inductive coupling onto the input power lines. Both linear and SMPS supplies have methods for dealing with each of these. Some are better than others.
