Okay, sort of new at this, hopefully I've worded everything so it makes sense...
1. How feasible is it to drive a pretty hefty power mosfet using only a standard comparator? Turn on/off delay is absolutely not an issue here, as long as it isn't up in the millisecond range or something. Knowing the maximum output current of the comparator, the threshold voltage of the mosfet, and the input capacitance of the mosfet, is there an easy way to calculate the expected turn on/off times? Is the output current of a comparator internally limited, or will I have to externally limit it?
2. I'm working on a battery-powered project that also uses a transformer. What kind of grounding considerations will I have to take on the secondary side? My case is non-conductive, so I'm assuming I'll have to put in some sort of large neutral conductor. How would I size this? Or am I completely on the wrong track here? Also, are there any grounding considerations for the primary (battery) side?
Thanks!
