I'm not an Electronics Wonk.
But as I Understand it, when you set a VV/VW mod to output More Volts than what the Battery can provide, the Board in your VV/VW Mod "Steps Up" the voltage to a Fixed amount. It then Stores this Higher than Battery Voltage. This Fixed amount is the Maximum amount of Voltage that the Mod can Output. This might be around 7 Volts depending on the Board/Mod.
Now the Board looks at what the User wants the Output Voltage to be, say 5 Volts, and calculates that if it supplies 7 Volts for about 71% of the time, then the Average over a Time Interval would be 5 Volts.
If the Board can do this 7 Volts on and then off Many (Many, Many) times in 1 Second, then the user will not Notice any On/Off. It just seems like a Constant 5 Volts.
I could be Off Base on this. Or this could be Old Technology. But that is how I Understand it.
I'm also pretty sure that someone who Knows More about things will come all and Explain things Better than I have.

^^ You're right. Maybe I don't want to destroy the beauty and mystery of this. Some things are better left unknown. Life is magical. It's a Christmas miracle.
Buck / boost voltage regulation. Basically, you can swap volts for amps as long as you keep watts law happy.
You're explaining PWM (pulse width modulation) and Hz (frequency measured in times [or pulses] per second).
Most modern mods work off of DC to DC buck or boost regulation.
In this (boost) regulation, the chip simply regulates current from the battery and converts it to a given or set voltage on demand via a voltage regulation chip or circuit.

A little further explanation.
PWM cannot increase voltage.
So like in the old school Provari and Vamo, they both had 6 volt set regulators.
In other words, they only output 6 volts.
In the case of the Vamo, the PWM circuit fired at 33Hz. So it pulsed 33 times per second leaving a very audible reverb in the coil.
Hence the rattlesnake effect.
While the Provari had a more smooth 800Hz combined with frequency smoothing to provide a flat curve.
This made the pulses unnoticeable.

It provides a lower resistance to the battery than that of the circuit to allow more current from the battery which then allows a higher voltage to the coil.

Sorry.
Last time I looked it up I was flooded with do it yourself instructions.
I was thinking that might help a little with the concept.
What they did was they went to drug stores collected disposed disposable cameras after the pictures were removed.
Then they utilize The Flash circuitry because it would take the voltage of a regular battery and store it at a much higher voltage to be used in an instant discharge to weld wires.
Not exactly the same as it's more of a capacitive discharge as opposed to a constant-current.
But I thought it might help just the same.
Either way a DC to DC voltage regulator uses a certain amount of wattage and just changes how its output.
In a boost circuit it comes from the battery at a lower voltage and higher amperage and is output at a higher voltage to make the wattage necessary. Which of course results in a lower amperage.

lets see... there is an item in a regulated mod called the PWM unit. it acts like a transformer, it can raise or lower the voltage from the source depending on the settings... as far as volts and amps, when you raise the volts above the batteries capacity, the available amps decrease... when you set the volts lower than the batteries capacity, the amps available "increase"..
for example... a transformer runs at 120V at 10 amps but can produce 1200V at 1 amp... or, 12V at 100 amps....
and, the transformer must be made to handle the amps too....
