a power converter includes a cable configured to deliver a source voltage and current to a load , where the cable is anticipated to drop some voltage as the load current increases . the power converter also includes a regulator having a feedback - adjusting transistor configured to gradually compensate for the dropped cable voltage as the load current increases . the transistor has a gate capacitance and a resistance forming an integrator configured to filter a volt - second product of an output waveshape of the converter to derive an average voltage correlated to the load current as the load current increases . the regulator is configured to increase a gate voltage of the transistor through a threshold region of the transistor and gradually turn the transistor on . the transistor is configured to apply an adjusting resistance coupled to a feedback sensing node of the regulator to increase the source voltage to compensate for the cable voltage drop and improve the load voltage regulation .
