Abstract
An example method may include generating an alternating current (AC) output at a power source within a borehole in a subterranean formation. An electrical component may receive a direct current (DC) output from a converter circuit coupled to the power source and the electrical component. One or more measurements corresponding to the power source, the converter circuit, the electrical component, or a protection circuit coupled to the converter circuit may be received. Blocking devices within the protection circuit may be selectively caused to block current flow in the converter circuit based, at least in part, on the one or more received measurements.
Claims20
A system, comprising:
- a power source providing an alternating current (AC) output;
- a converter circuit that receives the AC output from the power source and provides a direct current (DC) output;
- an electrical component that is coupled to and receives the DC output from the converter circuit;
- a protection circuit coupled to the converter circuit, the protection circuit comprising one or more blocking devices that selectively block current flow in the converter circuit;
- and
- an information handling system communicably coupled to the blocking devices of the protection circuit, wherein the information handling system controls operation of the blocking devices based on measurements from one or more sensors coupled to the power source, the converter circuit, the protection circuit, or the electrical component.
