1. A system for supplying electric power to a downhole load in a wellbore, comprising:
a downhole high-impedance alternator supplying power to the downhole load, the downhole high-impedance alternator having a predefined minimum reactance and a predefined minimum resistance; wherein the predefined minimum reactance and the predefined minimum resistance are sufficiently high to cause the high-impedance alternator to emulate a current source over a given output voltage range.
