MOSFET switching time advice.
Hello, I am building an H-bridge to drive a peltier cooler, and I am trying to figure out what switching time should I aim for. Now I know some may consider it a cardinal sin, but I use GPT, I'm a wall and breakers kind of sparky, my finer electronics knowledge is rusty, and somewhat basic. My idea is that since I have a few analog sensors around, and the faster a MOSFET switches the more noise it produces, I'd want it to switch slower. Power losses are not that significant, because at most I'd be switching it once or twice a second, more likely every few minutes. I look at the Safe operating area graph, and see that at my loads 10ms would still be well within safe margins for the MOSFETs I'm using, and decide to go with much lower time like 1ms just to be sure, I calculate the current I need to achieve it, triple it because switching MOSFETs is supposedly inefficient when slow, although I can't find exact estimates on just how inefficient, I end up with a huge resistor, when GPT has been telling me to use something orders of magnitude smaller. I know that the bot is limited and sometimes quite irrational, but he keeps insisting on couple hundred ohm resistors no matter what, which makes me think that everyone uses them, hence the training data, which makes me think there's a big reason that I'm missing. Can someone much better versed in this explain to me exactly what pro knowledge that's missing from the datasheet is eluding me? I have spare parts, and they are pretty cheap, but I'd prefer not to build the whole thing and immediately destroy it because I'm missing a key insight or because an AI has hallucinated me into the wrong solution. Thanks for reading, and thanks for any advice you'll provide me.
