Claim 0:
1. A system comprising:
a drive voltage source;
a control voltage source;
a high voltage source having a voltage that is higher than a voltage of each of the drive voltage source and the control voltage source;
a first transistor configured to provide a drive voltage from the drive voltage source to a coupled inductor upon switching of the first transistor by the control voltage source, the coupled inductor configured to receive the drive voltage and to generate a voltage output; and
a second transistor configured to receive a switching voltage generated from the voltage output, the switching voltage having a higher voltage than the voltage of the high voltage source and usable to isolate the high voltage source from a load positionable downhole in a wellbore by switching the second transistor.
