Abstract
Method and apparatus are disclosed for controlling a high voltage power supply. An example vehicle includes first and second power supply buses, a high voltage power supply coupled to the first and second power supply buses, and a high voltage controller. The high voltage controller is configured to control the high voltage power supply, detect a short circuit on the first power supply bus, and responsively change a power source of the high voltage controller by activating an opto-isolator and one or more smart FETs.
