pwm in closed loop

[LVKB]

I have a switch mode Power Supply that has two modules. I would like to be able to test the modules separately. One module is the power converter section and the other is the pwm control section. My question is can I control the power converter module using Labview and a 6020E series Daq Card using the pwm function in a closed loop? I guess specifically I am asking if the software/hardware is fast enough to really simulate my actual pwm control hardware?

The PWM function should work fine. Check out the DAQ examples for counter timer PWM functions. The second part of the question is closed loop control. How fast do you need to close the loop? How accurate does the loop need to be? 6020 Certainly you can close the loop at low rates (10 Hz for the 6020). Higher rates can be achived but you have to look at the requirements tighter and the communication overhead of the 6020
