Voltage Regulator with Virtual Remote Sensing

摘要: An automatic voltage compensation circuit in a regulator compensates the output for drop along lines leading to remote load. A load capacitor is connected across providing low impedance during test phase of regulator. In one embodiment, phase, current changed up or down small percentage (e.g., 10%). As result, changes due only line resistance since bypassed by capacitor. The at full then derived detecting change (a fractional drop) and multiplying it. normal mode resumed, added either compensating feedback loop adding
