Application: if loading-based, line-drop losses in a yacht are such that locations remote of the
converter and Ship's Bus experience undesirable, lower-than-expected voltages, the Nominal
Impedance Duty Cycle can be lowered via this control to increase output voltage. AGC
(Automatic Gain Control-see page 49) must be disabled when using this function or the modified
voltage level will be re-compensated by it. Initially, a small change (start with 5%) should be
used in conjunction with re-measurement at the remote location to determine the correction
needed. Drastic changes in Duty Cycle will result in equally drastic voltage changes. Transfer
Impedance is usually only modified by factory trained personnel when commissioning a
converter. It can be used to fine-tune the Seamless Transfer function.
