Abstract : The adverse effects of the impedance of long varying impedance connecting lines used in pulse width modulated power amplifier are eliminated by means of a dual input differential amplifier that senses the line voltage drops in the connecting lines and combines them into a line voltage drop compensation signal that is applied across the power amplifier inputs. This line voltage drop compensation signal raises the output of the power amplifier by the amounts needed to null out the line voltage drops. (Author)
