Ok, I've decided on a long term project of writing HTML JavaScript calculators for just about every calculation the 4hv community will ever need. I havnt done JS for a long time, but I brushed up on my skills inspired by the thread "igbt speed" that gives you capacitance and drive power required to switch gates at a given frequency.

I am doing this more so that I can increase usability of existing calculators towards us folks that sometimes use unconventional methods in our power electronics, and also so that the math we do can be verified and error free in a shorter amount of time.

Plus it makes the strange random calculations that are usually only done only once or twice replicable. So bring on the formulas! I'll do some of the ones that pop into my mind daily when the need arises, but other than that, 4hv will tell me what 4hv wants cheesey

Also, if anyone else who knows JS and HTML wants to pitch in, let me know so I can give you some of the HTML requirements to make all the calculator uniform in appearance.

Do capacitor current over time as it charges/discharges

Not sure which one youre talking about, I = (Vs - Vc) / R? Y over X implies a graph which i'm not too fond of. I'll try to keep this limited to input and output.

Just before it's too late, I'll ask that people post a formula, and the I/O that's desired.

This is a great idea :)

I recently asked for two formulas : Link2

Make a TC calculator, like JavaTC or TeslaMap but now it has every other calculator you'd ever need. :P

got the pages set up, and the gate drive calculator uploaded: Link2

because this is just something i do in my free time, it wont be very fast. nobody really 'likes' to sit and code hours on end tongue

and dont mind the rest of the site, cause i have to take down the entire thing and recode it... this was from before i knew anything other than html.
