Abstract
A direct current to pulse amplitude modulated ('PAM') current converter, denominated a 'PAMCC', is connected to an individual source of direct current. The PAMCC receives direct current and provides pulse amplitude modulated current at its output. The pulses are produced at a high frequency relative to the signal modulated on a sequence of pulses. The signal modulated onto a sequence of pulses may represent portions of a lower frequency sine wave or other lower frequency waveform, including DC.
