The change in output voltage that occurs when the load (at a specified power factor) is reduced from rated value to zero, with the primary impressed terminal voltage maintained constant.
A measure of how well a rectifier battery plant can control the steady state DC output voltage under two extreme conditions: (1) Vo at no load current with the input AC voltage at the designed maximum value, called Vomax; (2) Vo at full load current with the input AC voltage at the designed minimum value, called Vomin. %Regulation = ((Vomax - Vomin) /(Vomax + Vomin)) x 100 Note: "±" is used to distinguish the above regulation formula from the classical equipment formula defined as: %Regulation = ((Vonl -Vofl) / Vofl) x 100 where fl = full load, nl = no load and Vin is kept at rated value.
