Abstract
A system that includes a first transistor to provide a drive voltage to a coupled inductor is disclosed. The coupled inductor can receive the drive voltage and generate a voltage output. A second transistor can receive a switching voltage generated from the voltage output to isolate a load positionable downhole in a wellbore from a voltage source.
