In case of a bipolar device and it's base thats ofc an entirely different story.
>wasteful to spend time
You're not 'spending time' on further charging the gate past threshold, the device is 'on' so further charging happens in parallel
>wasteful
See above.
>If you have and recommended reading
I can give plenty of literature advice but none of it will be
>advanced
since without trying to insult I really feel you need to understand and especially experience some basic issues and remmedies to begin with.
On a sidenote if you really want to get a starter on (gate) driving waveforms check out the BJT based circuits for the horizontal deflection in late, very large CRTs.
>designing motor driver
like I said that's one of those things I'd do. Because you can get some hands on experience without diving into things like unclamped inductive switching first thing only to be looking at the scope totally confused.
>buck converter
Yeah I went through their files and must say I appreciate it's one of the very few projects that do the label 'open source hardware' justice.
>capacitive unit with boost
It's never purely either. The inductor unit will always rely on the spark gap and other parasitic capacities. Without you couldn't even simulate that stuff. And it would break the matrix if you built that. But yeah you could just add more C to that up to where it determines the characteristics of the output. But is that worth doing? You still need caps that survive the abuse. If you want to stay around 100V why even bother. If you want to go kV thats going to be expensive caps.
>a big inductor
Come on now. Thats not the way to go. I'll leave it to you to figure out why.
>laminated MOT
Picrel is the response of some laminated choke when you vary the current going through slightly. Probe is 1:10. I'd say it can definately store the energy you want and produce the open gap voltages you want. But you want a small inductor.
>slowing the clock
Good call again. Prescaler?
