user Programmable converter control for type testing and combined testing of AC Traction motors
we are planing to establish type test facility for AC Traction motor as per IEC 60349 and combined test facility for AC drives for Transportation application as per IEC 61377 in our lab. These IEC calls for testing of traction motor with actual Converter are converter closely resembling the actual one. The availability of actual converter is not ensure. Thus we are trying develop a converter which PWM patter and speed control alograthim shall be programmable by user. We already have Power modules of converter. Can some one suggest for controls hardware and software.

Naseem, do you like to test a small AC scooter at low voltage or a big train at medium voltage? Power modules are too different!

If you are looking for a flexible controller for your custom power hardware, there are maybe many solutions. One of the most famous rapid prototyping boards used in motor control is dSPACE (DS1103, DS1104). NI also has some solutions.
If you are going to develop your own boards, there are many development kits from uC manufacturers like TI, ST, Freescale, which could be used as a reference for control HW and SW.
Of course, as Mario says, power level matters...

Thanx for response, Mario and Sandro. AC traction motor with power rating of 200 KW to 1.5 MW , rated voltage of 1200 to 3000 V, frequency 0 to 250 Hz will be tested. Mr Sandro, will you pl give some more details of solution available with NI.
