ABSTRACT:
A system and a method that uses primary side sensing to regulate the output voltage at a cable end without any remote sensing of cable connections back from the load. This is accomplished by approximating the current from the control voltage in the control loop through the relationship that defines the Ton time in terms of the control voltage Vc. Once the approximation of the output current is known, it is multiplied by a known fixed cable resistance, and this value is subtracted from the feedback sensor output before it is subtracted from the digital reference. This forces the regulator to raise the output voltage by the amount of drop across the cable, causing the output of the cable to be maintained at the targeted regulation point.
