Bioelectrification

In 1990, William Lyman and Steven Kaali found that they could neutralize HIV by subjecting infected blood to a very small direct electrical current. The virus itself was not destroyed, but the current affects the outer protein coating in such a way to prevent the virus from producing Reverse Transcriptase, which blocks the virus from being able to infiltrate other cells.

Implementations
There have been a number of patents for devices that could use this technology to treat blood, such as US Patent 5,188,738, however it would be incredibly expensive since all blood would either have to be pumped outside the body, or devices would have to be implanted in the body that would have to be moved frequently.

Robert C. Beck, claimed to have designed a device that could use current outside the body. He has claimed that the FDA is against "curing", so he released the circuit design so that anyone with minimal electronics experience could help themselves.
