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.
