Abstract
A DC current driver includes a DC current drive circuit configured to provide a DC supply current and receive a DC return current. A switch is coupled in series with the DC return current, and a supplemental power supply is coupled in parallel with the switch and configured to provide a supplemental voltage. Opening the switch diverts the DC return current through the supplemental supply and closing the switch causes the DC return current to bypass the supplemental supply.
