In this case, increased pulse frequency would equate to higher motor speed since it is the primary motor pulse that would be modified.
This method would put a MUCH larger strain on the FETs since as the carrier pulse increases in frequency as motor speed increases, the carried pulses would need to increase in frequency as well to maintain the set duty cycle at a resolution suitable enough not to affect the efficiency of the system.
......Did I just say that??
