6.2.1 Phase Compensation Flow Diagram
The following flow diagram shows the implemented of phase compensation using the CDB5484U and a PC
as the controller. The MTE Meter Test Equipment source is used to provide the source voltage and load current
with a 60º phase shift (PF = 0.5). Each step of the flow shows the CDB5484 GUI screen capture of execution
and reading results. The register writes and reads are all identified for easy compares to the GUI screen.
