Abstract
A power transmission system for use with downhole equipment in a borehole includes a power source that is positioned at the surface providing a DC power supply, a downhole DC/DC converter and a two-conductor cable connecting the power source and the downhole DC/DC converter. The power transmission system receives the DC voltage supply as an input and provides an output DC supply at a different voltage to the DC power supply for provision to the downhole equipment.
