3-phase inverter using Infineon CIPOS module?
(1/2) > >>
mrflibble:
While browsing Mouser for some other stuff, I came across some interesting 3-phase inverter modules from Infineon. A single package containing all the major components for driving a 3-phase motor looks pretty nifty. Does anyone have any experience with these Infineon CIPOS IPM thingies? I did a search, but could not find any previous posts on the forum about it. So, thoughts / comments / experiences?

Haven't had a need for one yet, myself, but IPMs have been around for years, in various ratings.  Typically a bit on the slow side, but quite adequate for motor control applications, say.

A use case I was looking at was as a simplified substitute for something like a Siemens Micromaster inverter of up to a couple of kW. Lets say in the 1.0-3.0 kW range. To bring that under MCU control the inverter is connected through RS485. But a relatively low cost module + MCU on one PCB would be preferable, if for no other reason that I could make a couple of those, so no need to swap the inverter around.

No doubt one can make more performant solutions using discretes, but there is something to be said for getting a working solution without the traditional learning curve punctuated by puffs of magic smoke. So far my H-bridge mucking about has been limited to 60 Volt supply, not 400 Volt...

When you say a bit on the slow side, in what way? Slow rampup/rampdown? Slow reaction to overcurrent?
Yansi:
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.

IPMs on the other hand are really nothing new and were used for quite some time already. No problems should be to find an IPM for a couple of kW power. (There are way bigger ones than this available).

Switching speed.

Overcurrent may be internal, or it may be up to you.  Depends how integrated of a module you're looking at.
