Other Parts Discussed in Thread: CONTROLSUITE
Hi,
I am going through a PSFB code in ControlSuite/development kits/HPSFBv1.1. In this particular code they are adjusting DeadBand on basis of Load by sensing Current Output(Gui_Iout).So can anyone please tell me the calculations for the change in DeadBand.
I am attaching the code snippet of that particular code
