SPWM using FPGA in NI myRIO

[johnsus095]

I want generate SPWM in FPGA using NI myRIO device, I did pwm with flat sequence method having Ton and Toff time. Please help me how i can compare sine wave and triangle wave in FPGA using LabVIEW for my myRIO device. This is for providing gate pulses to an single phase inverter.

Hello johnsus095,

Could you please clarify what did you meant by "compare sine wave and triangle wave"?

Sorry to interfere in your conversation, but I also have the same question.

I guess what he meant was, a sinusoidal modulating reference of frequency 50Hz will be compared with a sawtooth carrier wave of frequency 10kHz, so when the sine wave is greater than the carrier wave a HIGH pulse is to be generated and LOW for other cases.
