you will be surprised, when you find there are even whole microcontrollers with integrated power transistors in one package, or even microcontrollers with integrated high voltage FET/IGBT drivers in the package.
Yeah, I noticed Infineon had several arm cores, but couldn't really find what I was looking for. Then again, I did not spend hours with parametric search, so entirely possible I overlooked something. Do you have a suggestion for "jelly beans" components in this segment? You can assume I am not looking for esoteric performance. Three phase motors, 1-3 kW range, rampup, ramp down, control speed, have things not go *boom*.
Switching speed.
Overcurrent may be internal, or it may be up to you. Depends how integrated of a module you're looking at.
Slower switching speed would be acceptable, within reason of course. I'm not looking for bleeding edge performance, mostly I'm looking for convenience in the form of lots of small subproblems already being solved.
Ideally I'd like something that handles:
* synchronous rectification, or basically single phase or 3 phase in, DC bus voltage out. 1 or 3 phase depending on use case.
* variable speed.
* overcurrent protection
* dynamic braking
* resistive braking (using external dump resistor)
* easy MCU control, primarily to be able to change speed. Think lathe variable spindle speed based on work piece diameter, that sort of thing.
That's about it really. Obviously there are the "Oh it would be nice if..." items, but lets keep it simple. In that regard, if it supports only 1 braking mode then that would still be doable. I realize that it would probably be cheaper to buy 3 chinese inverters, but where's the fun in that.
