I have what I think is a rather unique application. A VFD running a Copeland scroll compressor, 5 tons, three phase, 208/230 dual voltage. The VFD is oversized, but running from a single phase supply, so I am curious if changing the output voltage to the compressor can vary in any meaningful way the extra load placed by the rectifiers and capacitors in the power supply from running in this configuration. Or, will the power output be so functionally equivalent that the input will not be much affected?
